macOS High Sierra

The silly name aside (sigh), it is really ridiculous that in 2017 Apple does still not allow us to update the last Beta build to the GM (Golden Master) via a delta update, and instead forces us to download and re-install the whole OS from scratch, again.

Not only for developers this really is a total waste of time (and bandwidth). There are already hundred small design details all over macOS and iOS that are not 100%ly right in the Apple eco-system anymore, this additional annoyances really add up to a way too long list in the meantime!

Testing the Beta on my 15″ Retina MacBook Pro (Late 2013) the graphic performance (e.g. editing videos, but also just browsing the web) was quite sluggish, stability awful, and there was even screen flicker and corruption during booting (hello? - where has atomic mode setting gone? ;-)

The machine run also significantly hotter and battery life was obviously much worse. If Apple did not hot-fix this in the last weeks before the GM release this might very well be the worst macOS release I witnessed to date :-/ #peakbugs

Update: after fresh installation (sigh), even the boot graphic glitches prevail:

Update: even the Arstechnica mentions “bugs” 9 times, and “issues” 10 times, too. Nobody would have let Microsoft get away with this, and we would have called it the worst Windows Vista release ever, … Just saying, …

Update2: iMovie still has the same problem as the latest beta installation before the GM. On my above mentioned 15″ rMBP with 4k display connected and internal display closed iMovie even crashes straight away on start-up:

Exception Type: EXC_CRASH (SIGABRT)
Exception Codes: 0×0000000000000000, 0×0000000000000000
Exception Note: EXC_CORPSE_NOTIFY

Application Specific Information:
-[QCCGLRootContext minimalSharedContextForCurrentThread]: Inconsistent state
abort() called

Surprisingly iMovie starts when I open the internal display in addition to the external 4k display. What?

Sick & sad. Really sad.
