Apple Mac mini (Mid-2011) Core i5 2.5GHz [mw] full review
Apple gave its smallest Mac an aesthetic overhaul in 2010, replacing the chunky, aluminium-and-white-plastic 2009 model with a sleek, aluminium-unibody model that was easier to upgrade, felt rock solid, and sported an SD-card reader and an HDMI port (the latter pleasing AV buffs immensely). But while the design of the 2010 Mac mini was a dramatic change, that model received mainly modest upgrades on the inside. It also came with a higher price tag: the least expensive 2010 mini clocked in at £612.
The latest version of the Mac mini sticks with last year’s design, but it gets a price cut while overhauling what’s inside. Though the iMac is clearly Apple’s flagship desktop, the 2011 Mac mini is quintessential Apple: beautiful, well-engineered, forward-looking, and powerful enough for most, with at least one design decision that will leave some people wondering, ‘Why?’.
Lightning and Thunderbolt
The Mac mini is again available in two models, with the less expensive mini starting at £529. This gets you a 2.3GHz Intel Core i5 processor (last year’s model used the older Core 2 Duo), 2GB of RAM, a 500GB 5,400rpm hard drive, and an integrated Intel HD Graphics 3000 graphics processor that shares 288MB of main memory.
Team up the Mac mini with a Thunderbolt display or if you’re feeling adventurous, the £699 mini can drive two Thunderbolt displays, daisy-chained
For £699, Apple ups the processor speed to 2.5GHz, the RAM to 4GB, and the graphics processor to a discrete AMD Radeon HD 6630M with 256MB of dedicated memory.
Both models replace last year’s Mini DisplayPort port with a Thunderbolt port that supports both video (resolutions up to 2,560 x 1,600 pixels) and data connections, as well as Mini DisplayPort displays. You still get a dedicated HDMI port that supports video (up to 1,920 x 1,200 pixels) and multi-channel audio. As with other current Macs, you can connect DVI and VGA displays with the appropriate adaptors – only an HDMI-to-DVI adaptor is included – and the mini supports both dual-display and video-mirroring modes when two displays are connected. If you’re feeling adventurous, the Radeon HD graphics processor in the £699 mini can drive two Thunderbolt displays, daisy-chained, while still handling a third display on the HDMI port, although you shouldn’t expect amazing performance.
The 2011 mini’s ports and connections are otherwise unchanged: one FireWire 800 port; four USB 2.0 ports; a Gigabit Ethernet port; an SDXC card-reader slot; and auto-sensing analogue/optical-digital audio input and output minijacks (which support Apple’s current iPhone headset with remote and mic). Even the inconvenient location of the SDXC card-reader slot on the back remains the same.
In terms of wireless connectivity, the Mac mini still has 802.11a/b/g/n wireless, but Bluetooth has been upgraded to Bluetooth 4.0, with a new low-power mode. The mini also includes a built-in mono speaker and an infrared receiver for the Apple Remote (not included).
CD or not CD
On the outside, the 2011 Mac mini looks almost identical to its predecessor, with an enclosure that’s 19.7cm square, 3.6cm tall, and made from a single piece of aluminium. A black-plastic panel on the back hosts the computer’s ports, and a circular, black-plastic door on the bottom provides limited access to the machine’s insides.
There’s one difference in the 2011 mini’s exterior that’s immediately noticeable though: it looks like last year’s Mac mini Server. And by that we mean the front of the new mini is missing the familiar opening of a slot-loading optical drive. That’s right, like the MacBook Air, the Mac mini doesn’t have a SuperDrive.
For those who still frequently use DVDs and CDs, this may be a deal-breaker. While many people view the Air’s lack of an optical drive to be an acceptable compromise that results in a thinner, lighter laptop, many of those same people will wonder why such an omission was necessary on a desktop computer that’s already among the smallest on the market. The cynical answer is that omitting an optical drive reduces Apple’s costs, both in production and shipping (the new Mac mini is about 300g lighter than last year’s). And in case you haven’t got the hint yet, Apple would prefer you to download your movies from iTunes.
But it’s just as true that Apple sees the optical drive as today’s floppy drive – an aging media format that’s quickly being replaced by USB thumb drives, broadband internet connections, and other technological solutions. And for some people, that may be true. After all, between iTunes, the Mac App Store, Lion’s electronic distribution, iCloud, Lion Recovery (discussed on page 22), Target Disk Mode, CD/DVD Sharing, and ripping movies on another Mac, many Mac users could get along fine without an optical drive.
Leaving out the optical drive also gave Apple more space to work with inside the Mac mini – room the company put to good use by adding features (four-channel Thunderbolt and, on the £699 model, a discrete graphics processor) and options (a dual-drive setup, discussed below, and, on the £699 model, an i7 processor).
Still, dropping the drive was a bit of a surprising move, given that a good number of Mac mini owners use the tiny computer as part of a media centre. If you do need an optical drive, Apple’s £66 MacBook Air SuperDrive works with the new Mac mini – it’s actually a built-to-order option on Apple’s online store. Even with the external SuperDrive, the £529 model is still £17 cheaper than last year’s mini.
Core i5 produces performance boost
Though some people will consider the mini’s loss of an optical drive to be a step back, few will argue with the other changes to the 2011 line. While last year’s Mac mini offered modest performance increases, the 2011 line’s Core i5 processors provide huge speed gains. We’re currently revamping our benchmark suite, Speedmark, to account for Lion and the latest Mac hardware changes, so we don’t yet have our traditional scores. However, we did run 10 updated components of Speedmark to get an idea of how the latest Mac mini models stack up.
In CPU-intensive tests, including our Cinebench CPU test and HandBrake MP4 encode, the £699 2011 Mac mini with the 2.5GHz Core i5 processor was more than twice as fast as last year’s 2.4GHz Core 2 Duo model. The new £529 2.3GHz Core i5 mini also left last year’s model in the dust, clocking in at approximately 45 per cent faster in the same two tests. For the other CPU-intensive tests, the new models were between 30 per cent and 50 per cent faster than last year’s, with the £699 2011 model slightly faster than the £529 2011 model across the board for CPU-intensive tasks.
Unfortunately, the Mac mini’s stock hard drive is still a 5,400rpm, 2.5in laptop model. Despite being up to twice as fast as last year’s mini in processor-intensive tasks, the 2011 mini models were only slightly faster in tests that involved reading data from, and writing data to, the hard drive. For example, there was little difference between the models in our iMovie-import test, and the £699 2011 Mac mini was only 15 per cent faster than the 2010 model in our folder-duplication test. Although we haven’t yet had a chance to test the new Mac mini models when booted from a FireWire 800 drive, we suspect that, as with last year’s models, this could provide better drive-related performance. We’re also interested to see how an SSD or a Thunderbolt drive (see ‘More options than ever’) will affect overall performance.
When it comes to graphics performance, our benchmark results were mixed. Thanks to its discrete graphics chip, the £699 2011 mini was nearly twice as fast as the 2010 model in our Cinebench OpenGL and Portal 2 tests; it was roughly 50 per cent faster in our Call of Duty test. But the £529 model, with its integrated graphics processor, was roughly even with the 2010 model in our Cinebench test and only 12 per cent faster in Portal 2. (The £529 2011 model was actually slower than the 2010 model in our Call of Duty test, although Call of Duty is an older game that was never optimised for Intel graphics. Newer games, such as Portal 2, perform much better with Intel integrated graphics processors.)
Benchmarks aside, we found the £529 model played Portal 2 well enough to be enjoyable, although there was noticeable choppiness at the automatically selected resolution of 1,280 x 800 pixels. If you plan to play games more than occasionally, the £699 model, with its discrete GPU and slightly faster processor, is a better bet. On the other hand, one area where the £529 model’s integrated GPU doesn’t seem to hamper it is in video playback. The lower-end mini had no problem playing 1080p video when connected to an HDTV.
We haven’t had a chance to test a £529 model upgraded to 4GB of memory, but based on real-world use of the two 2011 models, we suspect that more RAM will result in better performance in some of the more-memory-hungry benchmark programs. It will certainly help if you tend to run several applications simultaneously.
The new minis are roughly as power-efficient as last year’s model, which used just over 9W when idle and less than 1.5W when sleeping. (The £699 model’s discrete graphics processor ups the overall power usage to a still-low 13W when idle.) The new models are also just as cool and quiet. Even when the fan was running full-tilt, during an extended gaming session, the £529 mini was no louder than the fan on the external hard drive we use for Time Machine backups.
More options than ever
When it comes to the Mac mini line, the biggest questions have always focused on options and upgradeability. As with most recent Macs, the build-to-order options for the entry-level model are limited. You can upgrade the £529 model to 4GB (£80) or 8GB (£240) of RAM, and you can opt for a 750GB 7,200rpm hard drive (£120). For the £699 model, you can increase performance by upgrading to a 2.7GHz Core i7 processor (£80); 8GB of RAM (£160); a 750GB 7,200rpm hard drive (£120); a 256GB solid-state drive (SSD; £480); and a combination of the 750GB hard drive and the 256GB SSD (£600).
This means you can configure an £1,539 Mac mini – and that doesn’t include a keyboard, mouse, or display. Few people are going to max out a Mac mini with all these options. But for those who actually need this kind of performance in a tiny package, it’s nice to know you can.
Unless you tend to work in only two or three applications – and even then, depending on the programs – we recommend upping the £529 mini from 2GB to 4GB of RAM. In testing the stock model, we regularly saw memory-related slowdowns once a number of applications were running; the £699 mini’s 4GB offered a much better experience.
Of course, as with most Apple RAM upgrades, you’ll get a better deal if you buy from a third-party vendor and install it yourself. For example, Crucial (www.crucial.co.uk) is currently selling 4GB of memory for the new mini for £32.39, with 8GB at £49.19. You can also get more RAM in your mini from third-party vendors. While Apple’s official specs say the Mac mini maxes out at 8GB, we’ve heard that US accessory vendor OWC is selling a 16GB upgrade – for a whopping $1,400 (£857) – that OWC claims is fully tested and compatible.
As with last year’s mini, memory installation is surprisingly easy: you just rotate the computer’s plastic base a few degrees counterclockwise and lift it off, pop out the two stock chips, snap in the new chips, and replace the base.
While Apple still doesn’t consider the Mac mini’s hard drive to be a user-upgradeable part, iFixit’s teardown of the 2011 model shows that replacing the stock hard drive is relatively simple. (Apple’s general policy with the Mac mini has always been that as long as you don’t break anything during the process, upgrading the hard drive won’t void your warranty.) This means that if you’re looking to increase the performance of the mini, or get more storage, you can save a few quid by skipping the build-to-order options and shopping for a 9mm, 2.5in laptop hard drive. At the time of writing, a 750GB 7,200rpm drive is just £89.87 from MacUpgrades (www.macupgrades.co.uk).
Connections are identical to last year except that the Mini DisplayPort port has been replaced by a Thunderbolt port that supports video and data connections, as well as Mini DisplayPort displays
In other words, while bumping the £529 Mac mini to 8GB of RAM (£160) and a faster, 750GB hard drive (£120) through Apple will set you back £280, going the DIY route will cost as little as £122.26.
As for other upgrades, the inclusion of Thunderbolt is a Really Big Deal, despite the fact that there aren’t yet many Thunderbolt peripherals on the market. As our benchmarks show, Thunderbolt is dramatically faster than even FireWire 800. We’re curious to see how the 2011 minis will fare when booted from a Thunderbolt drive or RAID array. Thunderbolt’s flexibility means that the new minis will have more expansion options than ever, including many of the same high-performance upgrades that will be available for Apple’s ‘pro’ computers. (It’s even possible for vendors to adapt PCI Express cards for Thunderbolt.
Road to Recovery
Given the lack of an optical drive, the new Mac minis obviously don’t ship with a system-restore DVD. Instead, if you ever need to reinstall Lion, you use Apple’s new Lion Recovery feature. The Mac mini’s hard drive includes an invisible partition called Recovery HD. If your main startup volume is having trouble, you can boot from Recovery HD (by holding down C-R at startup) and then repair the startup volume – or even erase it, reinstall Lion, and restore your data from a Time Machine backup. (To reinstall iLife ’11, which is preinstalled on the new Mac minis, use the Mac App Store.) Of course, this means Lion Recovery requires an internet connection.
We had an opportunity to use Lion Recovery while testing the new Mac mini. When we tried to use Migration Assistant to transfer data from a 2010 MacBook Air to a new mini, the procedure would stall – for hours – at the ‘under a minute left’ stage. We eventually gave up and restarted the Mac mini… which left it in a non-bootable state. We rebooted into Lion Recovery and tried to repair the hard drive using Disk Utility, but that didn’t fix the problem, so we erased the drive and reinstalled Lion. Lion Recovery doesn’t include the full Lion installer – that data must be downloaded from Apple on the fly. Over a cable-modem connection, using Ethernet, the process of downloading and installing Lion through Lion Recovery took just over an hour.
But what if your hard drive has hardware or partition-map problems that prevent you from booting from the Recovery HD partition? The Mid-2011 Mac mini and MacBook Air models – and any new models of Apple’s other lines that are released going forward – include a special feature called Lion Internet Recovery. These Macs can boot directly from Apple’s servers, at which point the software tests the computer’s memory and hard drive to make sure there are no lingering hardware issues. Assuming those components are fine, Lion Internet Recovery downloads, and boots from, a Recovery HD disk image, at which point you get the standard Lion Recovery options. We haven’t yet had a chance to test Lion Internet Recovery.
Lion Recovery and Lion Internet Recovery are welcome features for troubleshooting, but the requirement to download nearly 4GB of data in order to reinstall Lion adds quite a bit of time to any system restore. It’s still worth keeping a bootable Lion-installer drive handy.
