Started after the last update to Mac OS 26.3 (beta) Also removed 2 recent instalments (Blackhole audio driver and kDrive/Infomaniak, but trouble is still there. 27" iMac 2020 (Intel) i7 3,8 Ghz AMD Radeon Pro 5500 XT 8 GB 24 GB RAM macOS Tahoe 26.3 (=beta) Tried restart in safe mode, checked fonts. Talked to aissistent to get a solution, but no ...) Thx for any advice, Pieter (not a developer so please kee pit simple 🙏🏻)
