The problem is that there are no external 2x displays on the market (apart from the recalled trainwreck that was LG ultrasharp 5k): https://bjango.com/articles/macexternaldisplays/ https://bjango.com/articles/macexternaldisplays/ Scaling is horrible on MacOS since it basically bumps up the 1x resolution to the next integer multiplier and then does a per-frame raster resize leading to performance drops, blurry edges and other render artifacts. Meaning that your only reasonable option was to run a 1x monitor without scaling. Now they killed that option too. Basically what they did, if your primary work machine was a MacBook hooked to a 27" display — is tell you "Buy an iMac and use Continuity". I mean, I'm all up for removing subpixel antialiasing at the point where everyone is running a 220+ppi monitor. However, we're not at that point yet. This is a horrible move that may cause me to drop the Mac as a development platform, since I'm looking at text for 8+ hours a day, and I'm not planning on shelling out 3k€ for an iMac or 2k€+ if they get back into the display business, just to fix something that they broke.
