Tidy MacCheck your Mac’s battery health
Your MacBook battery is healthy if macOS shows Condition: Normal and Maximum Capacity is 80% or more. Apple rates Mac notebooks for 1000 charge cycles. Paste the Terminal output below to see where yours stands.
system_profiler SPPowerDataType | grep -E "Cycle Count|Condition|Maximum Capacity"
Keep an eye on your disk, too
Tidy Mac doesn’t check batteries, but it watches your storage: free space in the menu bar, a 30-day trend, and a notification only when the disk is almost full. $9.99 once, 2 Macs.
How it works
Open Terminal (Applications › Utilities), run this command, and paste what it prints:
- Cycle Count: one cycle is 100% of the battery used, in any number of charges. Compared with Apple’s rating of 1000 cycles (Apple Support).
- Condition: Normal, or Service Recommended when the battery holds noticeably less charge.
- Maximum Capacity: today’s full charge as a share of the original.

Questions
How do I check my MacBook battery health?
Choose Apple menu › System Settings › Battery and click the info button next to Battery Health. For the cycle count and exact capacity, run system_profiler SPPowerDataType in Terminal, or paste its output into this checker.
What is a good battery cycle count for a MacBook?
Apple rates Mac notebooks from late 2009 onward for 1000 cycles. Under about 300 is light use, 300–800 is normal for a few years, and near or above 1000 you’ll usually see less battery life.
What does “Maximum Capacity” mean?
How much charge the battery holds compared with when it was new. Apple designs Mac batteries to keep most of their original capacity through their rated cycles; when macOS shows “Service Recommended”, the battery is worth replacing.
