Reflows – an update Spring 2017

So we have offered a reflow service for many years now. If you are not familiar with what a re-flow is we have a blog post here which may help, and an early update here.

Typical symptoms of a GPU issue which may be resolved with a reflow are that on starting up you get an Apple Logo (showing the Mac has found it’s OS and started to load) – getting a progress bar (in 10.10+) which goes to three quaters along and then getting screen flicker to a grey screen. At this point the Mac stops responding or reboots. Usually these will work in “Safe Boot” (with the shift key held down on startup) – as they do not load the full GPU driver.

We have seen some newer Macs with these symptoms appearing and thought it worthwhile to share these with you:

MacBook Pro 2011 (MacBookPro 8,1; MacBookPro 8,2 and MacBookPro 8,3)

These were covered under an Apple Repair Extension Agreement -for Graphics Issues ranging from pixel discoloration to black screen on startup. This originally expired in Sept 2016 but was extended at the last minute to Dec 31st 2016. This has now ended (unless you are less than 4 years from date of purchase – in which case please see here and get booked into an AppleStore Genius Bar ASAP).

These suffer from a different issue from earlier MacBookPros / iMacs – it appears to be an issue within the GPU Chip to do with the solder borders internally. The Reflow “cookbook” for these is a little hotter and a little shorter than the ’08s or ’09s and works very well indeed. We have done a good number since the REA ended and have had none come back under warranty – so are hopeful this is a longer term fix than the earlier models. Only time will tell!

As ever this is a fixed cost repair – £ 85 + VAT and del. It usually only takes 1-2 working days once in our Sawston workshop.

Mac Mini 2012; (MacMini 6,1 and MacMini 6,2)

These Mac Minis seem to display the typical Graphical issues; pixelated color spots or black screen on startup. Symptoms persist even with good RAM, HDD, PSU or Display adapters.

We have completed a few of these reflows – they are more involved than the MacBook Pros as they need a little more stripping down and have had good results following the 2011 MacBook Pro “Cookbook”. They appear to suffer from the same internal GPU issues. We have not created a code for the website yet, so please feel free to call us to discuss your Mac Mini.
