Thunderbolt glitches with Macbook Pro 13" 2012
Hi everyone,
Having searched the forum and not finding anything concrete related to what I'm experiencing on my daily endeavours, here are my list of experienced glitches;
Whilst running Mavericks I would get a very bad wake from sleep glitch on the external thunderbolt screens; I had two attached at the time - they worked beautifully until you let the machine sleep, then when you woke it, it was almost as if it hadn't woken correctly and one of the two screens had jumping distorted lines across it. Strangely, I was able to make the lines go away temporarily by grabbing a moving a window around, however when i stopped moving the window the lines would pop back again after a minute or so.
I had the same glitches with my bluetooth mouse - and it's definitely software related. Every time i wake from sleep and there are processes which are intensive (such scanning mail all at once across 5 accounts) or updating something then the mouse would 'lag and hang' - again, something I'm almost 100% sure is software and OS related not hardware.
Come Yosemite, i thought ok, troubles away and do the update. So far so good.
Having moved one thunderbolt display to the office and only using one at a time, its much more stable, however i have noticed two things;
Boot up in clamshell - i.e. open laptop, press power whilst connected to thunderbolt (as i did with mavericks) and things would come one, except having laid the laptop in clamshell mode down now (at home, or stood in its dock at the office), there are no peripherals connected - no mouse, no keyboard, no trackpad. I have to open the macbook and log in using the built in keyboard and trackpad, then close to clamshell mode again. Effing frustrating.
Even worse though is when you sleep in that mode, and disconnect the thunderbolt (i.e. leave the office) and get home, plug in to thunderbolt again, and 'wake' the machine up - again, everything is frozen - i can click around, but nothing actually responds; i can click windows, menu items, but keyboard and mouse clicks don't respond (almost like Finder needs a killall.dock terminal process run) however you can't do that - you can open terminal, but you can't type... i assume this is perhaps the "sleep-freeze-bug-gate"...
Aaaannnywways, though my venting might help someone know they're not the only ones...
any help appreciated.
I've done the usual like PRAM and resets, etc, disconnected battery (even changed out SSD's to check it wasn't that, and it wasn't).
