MacBook Air SMC Update v1.8
This update addresses a rare issue on some Apple notebooks where a battery that has accumulated more than 1000 charge cycles may unexpectedly shut down or stop functioning.
I have an MacBook Air (13-inch, Mid 2011) running El Capitan 10.11.6 (15G22010).
I have ignored this update for a long time because my battery, though not in good health, has 332 charge cycles, nowhere near 1000 charge cycles.
Do I need to apply this update at all? Should I apply it anyway?
If I install High Sierra 10.13, do I need to apply it before upgrading? Or will the OS upgrade make the SMC update obsolete?
