Apple Intelligence is now available on iPhone, iPad, and Mac!
Has anyone had this problem?
My mother was prompted to do the latest update (to OS 10.10.5) and update her Safari, but now her Safari has a cross through it and won't open.
It says "You can't use this version of the application "Safari" with this version of OS X".
Has anyone had anyting similar? It seems odd that Mac would offer an upgrade that makes its own products obsolete...
Any advice would be much appreciated!

I suggest you reinstall the OS. Do a backup, preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair Disk and Repair Permissions until you get no errors. Then re-install the OS.

Hello, and welcome to Apple Support Communities billykioso,
We can your mom us unable to use Safari on her MacBook due to the prohibitory symbol.
For Yosemite, the latest version of Safari is 10.1.2. What happens when you removed the Safari 12.1.1 package? Does it allow her to get back on Safari after restarting her Mac?
If not, let's see if the steps include here help: Update or reinstall Safari for your computer. You might have to reinstall the macOS too: How to reinstall macOS. We wanted to make sure you have these steps if needed.
Keep us posted on the results! We're hoping this helped.
Many thanks for your reply ! Yes, Safari 12.1.1 is not recognised, but I don't understand why the Mac prompted her to update her Safari, as this is what made it unusable.
I tried to delete Safari but it won't let me (it says it's part of the system). So I downloaded Safari 10.1.2 and installed it. It made the successful installed sound, but the Safari icon remained the same and it still won't open (see pic).
It looks like she's forced to either reinstall macOS or simply use another browser, which seems easier.
Do you know if this was an issue with other Mac users? i.e. were others prompted to download incompatible versions of Safari? It seems this is where the problem started.
I did disk utilities as you said, until no errors came up. But when I try to reinstall the OS and press 'continue' it says "A required download is missing" so I can't complete it. Do you have any suggestions?
OK, I ignored the reinstall and just used Time Machine to back up instead, so computer is working again now. I'll be reluctant to do auto updates in the future but thank you for your help in resolving this!
(update) Now it seems that Photos won't open either...
You are welcome.
