Does your update advice regarding Tahoe 26.4 “it’s probably time to identify a time to make the jump” still hold if the device that is currently running Sonoma is a 2020 13-inch MBP with a 2.3GHz i7 and 32 GB of memory? Won’t it be kinda slow under Tahoe?
Did anyone notice this new feature added to macOS 26.4:
“New Feature in macOS 26.4: Automatic Remounting of USB Drives after Sleep
macOS 26.4 has introduced a significant enhancement regarding the handling of USB drives. This feature automatically remounts unmounted local USB drives when the system wakes from sleep.”(Quoted from DuckDuckGo AI “Search Assist” search results)
Since the macOS 15.3.2 update I regularly unmounted three volumes on two locally attached USB drives used primarily for backups. As I reported in another TidBITS-TALK post, after installing 15.3.2 Finder became ‘sluggish’ performing simple operations like copying and moving files and folders, dragging URL’s from browsers into Finder, etc. After implementing my morning unmounting routine, the sluggishness rarely happened.
Since I first Installed macOS 26 (26.4) on 03/28/26 and learned the ‘remounting’ was a feature vs. bug, I’ve noticed a marked absence of the ‘sluggishness’ - I’ve only noted a couple of ‘sluggish’ times.
I suspect 26.4 includes improvements to how the OS handles USB drives. When the sluggishness first appeared one 3rd party app developer I talked to said macOS 26 introduced some problems in this regard.
I really don’t know how Tahoe runs on an Intel-based Mac, but it may be easiest to stick with Sequoia for now, particularly if you’re considering getting an Apple silicon Mac. (Which will be so, so much faster.)
Has anyone tried Tahoe on the few Intel-based Macs that are still supported?

Just an FYI that there is a bug in iOS and iPadOS 26.4 with CloudKit that prevents these devices from syncing content with iCloud in the background as they should. In reading through this it may also affect pushed notifications for these apps.
This isn’t an issue with iCloud Drive, but with apps syncing changes in the background using the CloudKit framework on iPad and iPhone devices. The issue is fixed with the 26.5 beta; hopefully it will be resolved for the stable release before 26.5.
I’ve read already a post from the to-do app Due that switching from iCloud syncing to Dropbox syncing fixes this problem for that app for now.

I use the Drafts.app. Usually, the sync between the Mac version and iPhone is near instant. Now it is very slow. Nice to know it will soon be fixed.
