Keyboard vowels not responsive with mojave.
I have a mid-2012 Macbook Pro with 8GB RAM i7 processor and graphic coprocessor. Never any hardware or keyboard issues before Mojave.
Since upgrading to Mojave, I have repeated issues with some vowels (especially i and o, but also others) not being responsive. Like REALLY not responsive. Like for 20 seconds not responsive. I try to type protein and I get prtn. So then I back up and tap the o several times, then HOLD it down for 20 or 30 seconds. Ah, then I get a pop up menu for all the variations of accented o's I have available. And then the o works for the rest of my typing session. After the first letter recovers from its 'stroke' the other vowels come back a little quicker, and then i am typing normally.
I have had an Apple employee tell me it is a hardware issue, but that makes no sense. (a) First happened with a software OS upgrade. (b) Only certain keys affected and always those that have accent option popups. (c) Recovers after the software popup appears. --- Pretty sure those are software, keyboard polling issue indicators.
It seemed to be worse before I turned off all the smart quote and accessibility sticky key options i could locate. But I think there may be another option I have not found or which has no off switch.
Anybody have any ideas? Similar problems?
