If that were all they were doing, nobody would be concerned. It’s the crapifying of the MacOS in order to make it work fine with a touch interface that drives everybody bonkers about the slow merge.
For less discerning users maybe the rough edges aren't that noticeable. But the point of choosing Apple products is you should be a discerning consumer.
That article mentions basically that they’ve heard that some apps crash a bit but it’s anecdotal and not uncommon with beta/new upgrades before a patch or two (not uncommon), and that he personally dislikes or has trouble with some of the transparency or other design changes.
Neither of those things worry me personally, and I think the previous user calling it a “crappification” is still somewhat of an overreaction. Obviously from an accessibility standpoint transparency/legibility is important but as far as I’m aware tweaks are being made and these things can also be turned off or modified in accessibility settings.
I understand. I have been using a Mac since 1984 and I actually like glass more than the flat aesthetic we have been through. I see it as closer to Aqua and a subtler skeuomorphic effort. I have reported to Apple some of the problems liquid glass has. I see Liquid glass as better than what we had before.
