1 Service battery after update to Monterey
HI
have a a strange situation with a A1989, had to replace the battery on the unit. After battery replacement battery show "service battery" on Monterey 12.4. It only does this on Monterey, Catalina 10.15.6 and Big Sur does not show this message. The battery charges and holds charge with no issue. Tried 3 new batteries and same result.
Steps taken:
SMC+NVRAM reset
Full DFU restore.
archive install
updating from a known working OS.
Can't get rid of the message on Monterey. Also changed the battery to board flex cable with a working one from a separate machine.
Any help would be appreciated.
