Hi all.
I have a MacBook Pro 15", model 5.1 (MC026LL/A) with a Samsung 840 Evo 256GB SSD. The AirportExtreme has device number 0x14E4, 0x8D. Had (and still have as spare) a Transcend SSD370 (512GB) SSD before, with El Capitan fully updated.
Installed High Sierra in a APFS volume and applied all the patches including 10.13.3. No major problems, everything seems to be working ok with only 2 minor issues:
- Sometimes corrupted video with Firefox 57.0.4 and 58 (eg, YouTube or Imgur GIFv). Sound isn't affected. If I fully reload page it will sometimes start playing ok, sometimes not. No problems with Safari. Using low power chipset GPU (Nvidia 9400). Haven't tried it with discrete Nvidia 9600GT.
- My old Speedlink SL-6376-SSV Saphyr Bluetooth mouse that works perfectly with El Capitan doesn't work with High Sierra. Is recognized but won't move pointer. Probably very old BT version, not supported anymore?
Have another BT mouse that works fine, a Lifetech Link Mouse (LFMOU029). Apple Keyboard (A1314) and Magic Trackpad (A1339) work fine.
Using it with a LG 25UM55-P UltraWide display, through a MiniDVI to DisplayPort cable, displays full resolution (2560x1080) perfectly.
Great job!!! Thank you very much!!!
Edit: viewing YouTube videos with Firefox sometimes freezes the image, progress bar and sound aren't affected. After a few seconds unfreezes and continues at present time.
Edit 2: Ok, after testing, found out that the freezing happens with 1080p60 and 720p60 videos. Other framerates are fine. Disabling Hardware Acceleration in Firefox has no effect.
Edit 3: Solved the problem. Type 'about:config' in the URL box, accept responsibility by clicking button, and search for 'media.mediasource'. There will be 4 results, they should be all as 'True'. In my case, 'media.mediasource.webm.enabled' was 'False'. After changing it to 'True', 1080p60 and 720p60 content won't freeze anymore (some jitter but acceptable).
Edit 4: Seems that the previous edit fix also solved the corrupted video problem in Firefox, yay!!!
