Could you explain, in purely technical terms, how a small animated image on the login screen 'bloats' the operating system?
First it's cached to your user profile - meaning it would take up a bit more disk storage, not to mention a bit of complexity to your user profile - especially if associated to an Active Directory or Open Directory domain - on top of KeyChain additions.
How specifically technical or how much storage space would be used - I don't know but I think what I typed gives you an idea.
More importantly why isn't:
Mail - Rules setup per mailbox per user NOT synchronized in iCloud?
Mail is an iCloud FIRST app from it's dawn, heck even from MobileMe era. Why is RULES and synchronization SO DAMN hard to resolve? IS every executive and employee at apple using a local client rules to move emails into a folder? does anyone at Apple fully USE iCloud rules and Mail and not see every IOS major update breaks rules sync?
Mine are simple:
Email from blah blah - move to Fitness/Online purchases etc.
Email with 'Track/Tracking/Shipping' in Subject line (I'd like Subject and Body btw) move to folder - Tracking.
these are VERY simple and I'm using the FULL email primary SMTP address.
Anytime you add multiple SMTP's in an iCloud MAIL rule - it'll break after a few days of working. Like how can apple be SO GOOD at FaceID, Touch ID, anything security related but email and rules and local to cloud sync is so challenging to them on THEIR platforms? This is embarrasing.
Honestly this feature ALONE I think would be used by a MUCH greater macOS, iCloud, iPadOS, WathOS, and iOS user base than animated memoji on macOS Montery.
Apple - Fix whats broken first before implementing new changes that add more to code and cause more issues to fix down the road. Wait a minute I think Apple knows this and THIS is WHY they avoid fixing bigger issues:
Mail:
iCloud Rules breaking.
no local client Rules to sync (from macOS, iPadOS, iOS native Mail client to sync on Mail in iCloud and across devices)?
iMessages in iCloud - remember this 6yrs ago?
^ STILL not fixed. It works ONLY on iPadOS, iOS, macOS but NOT on WatchOS.
>> more specifically SMS and iMessage sync (for arrival, read, or delete) works on macOS and iOS and iPadOS ...
SMS messages does NOT sync.
* actually in fact as far as prior to Big Sur macOS iMessages would say if you deleted on iOS.
So FIX what we NEED and use daily vs adding frivilous icandy features.
