When OPTIMIZED_CHARGING_OFF on MacBook Battery, what causes it and how to fix bites you on MacBook Battery, the first instinct is to open a ticket. Most of the time you do not have to. The steps below are the ones Apple Support and Apple Business / Enterprise Support would walk you through on the call.
What optimized_charging_off on macbook battery, what causes it and how to fix actually involves on MacBook Battery
The OPTIMIZED_CHARGING_OFF error from AWS typically surfaces with the message "Optimized Battery Charging turned off". The error code itself is what you grep for in AWS re:Post or in AWS Support cases, not the human-readable line.
On MacBook Battery, this most often comes from one of three causes: a missing or restrictive IAM permission, a service-level limit you have hit, or a transient AWS-side capacity issue. The fix path differs by which.
The rest of this page is the structured fix path. Start with diagnose, then remediation, then the automation options so you do not have to do this by hand the next time it surfaces. Verify and safety sections at the end are the discipline that keeps the fix from regressing in production.
Diagnose first, fix second
Run id -un; defaults read MobileMeAccounts; profiles list first. About one in five 'why does this not work' tickets are actually 'I am in the wrong account' or 'my session expired and the SDK is using stale credentials or ADC pointed at the wrong project'. The 5-second sanity check costs nothing and saves real time when the answer is that simple.
Check Activity Monitor / Jamf inventory Logs for the calling service. Lambda, ECS, EKS, Step Functions, API Gateway, and most managed services write detailed traces to Activity Monitor / Jamf inventory Logs under predictable log group names. Use Activity Monitor / Jamf inventory Logs Insights with fields @timestamp, @message | filter @message like /ERROR/ | sort @timestamp desc | limit 50 to surface the most recent failures.
Reproduce the failure with the Terminal commands (defaults, plistbuddy, killall, sudo, system_profiler) and Apple Configurator 2 / Jamf APIs / MDM commands in --debug mode. The full SigV4 request payload it emits, plus the exact endpoint URL it resolved to, is what Apple Support and Apple Business / Enterprise Support uses to verify policy, region, or parameter issues without you having to share IAM credentials. Save the debug output to a file with ... --debug 2> debug.log and you can search it for the failed aws.request entry.
Solution-focused remediation path
If you cannot reproduce the failure consistently, the cause is probably a race condition or a session-cache issue. Run the call with --profile set to a fresh STS session, in a different region you control, with a single concurrent request. If it works there but fails in your normal setup, the difference is the bug.
Most MacBook Battery failures fall into one of three buckets: IAM permission gap, networking path break (security group, NACL, or VPC endpoint policy), or service-limit / quota hit. Run that mental triage first - it covers around 80 percent of real-world cases. If the failure does not fit any of the three, it is likely a service-side regression worth opening a re:Post or support ticket for.
For IAM and STS issues, the timing matters. STS sessions can take up to 60 seconds to propagate after creation. The first call right after assume-role can fail with a permission error even when the policy is correct. Add a small retry with backoff before treating the first failure as definitive.
Automate this fix so you do not do it twice
Build a Self Service item with manual approval for risky fixes
For multi-step fixes that include a destructive action (Reset NVRAM, delete keychain, erase user data), publish the fix as a Self Service item in Jamf Pro or Kandji. The user clicks one button, the script runs, a notification confirms success. Couple it with a Jamf Pro approval workflow if your security model requires a second-person sign-off before any destructive step runs. The audit trail lives in the MDM change log with the requester and approver identity attached.
Add a Smart Group + webhook so you catch the next occurrence
The cheapest way to never see the same incident twice is a Jamf Pro Smart Group that watches for the symptom (specific extension attribute value, specific OS version, specific app build) and fires a webhook into Slack, PagerDuty, or a Jamf-API-driven Lambda when the count drifts above your normal baseline. For MacBook Battery, the relevant extension attributes live under script-evaluated checks - defaults read outputs, system_profiler values, or a log show grep against macOS unified logging. Set thresholds against observed normal, not against round numbers.
Automate the fix in Terminal with defaults, plistbuddy, and system_profiler
On macOS, the most reliable repair primitives are the built-in Terminal tools. defaults read reveals the current preference state, defaults write changes it, and killall cfprefsd forces the preferences daemon to flush so the new value actually takes effect. /usr/libexec/PlistBuddy handles structured plist edits when defaults is not enough. For hardware and inventory checks, system_profiler with the right datatype is the canonical read; for example SPHardwareDataType, SPNetworkDataType, or SPInstallHistoryDataType.
# Template - replace with your actual key path
defaults read com.apple.macbook 2>/dev/null | head
sudo killall cfprefsd
/usr/libexec/PlistBuddy -c 'Print' ~/Library/Preferences/com.apple.macbook.plist
system_profiler SPHardwareDataType -json | head -40
Common pitfalls and what to watch for
The pitfall most teams hit on MacBook Battery is moving too fast and skipping the read-only validation step. Before any write, list the current state and save it. Apple iCloud and APNs are eventually consistent (changes can take 1-15 minutes to propagate) for many resource types, so the validation snapshot is your only reliable reference if you need to undo. Save the output of the describe call to S3, not to your laptop.
Second pitfall: confusing IAM permission errors with networking errors. AccessDenied can be IAM (policy missing), networking (VPC endpoint policy blocking the call), or KMS (key policy missing). The error string looks identical for all three. Distinguish by looking at the Jamf Pro change management entry or Apple Business Manager audit event's errorCode and the encoded authorization message; do not assume IAM is the culprit just because the message says AccessDenied.
Verify the fix worked
- Watch for 24 to 48 hours. Activity Monitor + macOS unified logging + Jamf inventory reports can mask issues with cached health for 6 to 12 hours, especially Cloud CDN and Cloud DNS.
- Capture the new state in a runbook so the next person on call does not have to rediscover this. Push it to Confluence or your team wiki, not into Slack.
Safety, rollback, blast radius
- Test in a non-production account if your environment has Resource Manager and Organization Policy or Cloud Resource Manager (organizations, folders, projects). The cost of one sandbox account is cheaper than one rollback meeting.
- Export the existing config before changing it. Most MacBook Battery resources support describe + export to JSON via CLI - capture that to source control before you start.
- Maintenance window discipline: if the change touches DNS, certificate rotation, or anything that emits TLS handshakes, line up a window with stakeholder notification, not a heroic mid-day swap.
FAQ
macbook describe-... first, then commit it before you change anything. A few operations are one-way (Cloud KMS key deletion past the pending window, region migration, account closure). Check the Apple Support article for the specific API before you commit.aws CLI or SDK calls - those almost always still work.References
