Magic keyboard adding charact-ers aft-er cert-ain keys on iMac Ret-ina 5-K INt-el i5--
t---------- b----- g- 5--- all have t-he prob-lem.
I have t-----------ried safe mode, swit-ching- off and power plug- out-, reb-oot-ing- wit-h Opt-ion, Command and P and R , upg-rading- t-o Mont-erey 12.7.1 , using- t-he cab-le t-o plug- in t-he keyboard .
Somet-imes aft-er a reb-oot- it- works ok b-ut only for a short- period of t-ime and t-hen it- g-oes wrong- ag-ain.
G_iven it- works sometimes it- sug-ge-st- it-s not- t-he keyboard and is th-e software instead. Ot-herwise I would just- b-uy a new keyboard.
Any ideas?
