Hello. I've tried to find some timers for Mac but none of them work or are too confusing. If you know of any simple timers for mac pls let me know. thx bye.

Either Llanfair, https://github.com/gered/Llanfair time split tracker ( https://dunnius.itch.io/time-split-tracker-windows ) or Livesplit one http://one.livesplit.org/

Have fun speedrunning!
