@marketing_2400 It is always a bit risky to immediately upgrade the operating system immediately once it is publicly available. On the system requirements page for Illustrator there isn’t even macOS 15 mentionened, yet. https://helpx.adobe.com/illustrator/system-requirements.html#ai-on-the-desktop

I usually wait almost half a year before upgrading my system, then most of the early issues have disappeared. Unfortunately it is quite cumbersome to downgrade macOS.

Log a bug here on the bug section of the forum and additionally also on Uservoice: https://illustrator.uservoice.com/forums/939477-illustrator-desktop-beta-bugs

I will try to involve someone from the Ai-team.

Looking forward to hearing from you.

Hi,

Nearly half of the Japanese fonts are unusable in Sequoia and Tahoe.
This fix requires support for Illustrator or macOS.

Also, in the case of Adobe Fonts, do not install the family.
If you do not install it, you can use it as usual.
