Command R or Alt, Command R not working on Macbook Air
All most tried all the variations to get into boot recovery mode, but nothing worked so far,
Power off - Power on - command R
Power off - command R - Power on
Restart Command R
Power Off - Alt command R - Power on
Power off - Power On - Alt command R
Disk utility erase option fade out...
Now i have tried to create a bootable installer by pan drive and downloaded Os bigsur through terminal in pan drive, but again the issue arise when i try to use the bootable installer & press alt key while restart or power on, again its not going int to recovery mode..
please suggest how can i turn on recovery mode if alt command r not working...
is it possible to do so by terminal....
