Swap usage explained GBs of swap normal on Mac Performance and Slow Mac sits in the most-reported issues list across r/aws, Apple Communities (discussions.apple.com), and StackOverflow. The recovery path is mostly known, the Apple Support docs just bury it under three layers of conceptual material.
What swap usage explained gbs of swap normal actually involves on Mac Performance and Slow Mac
This task on Mac Performance is one of the more searched operational topics on AWS in the last 12 months. The procedure below is the path that works in a current AWS account with default IAM and standard VPC config.
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.
Signal review
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.
Look at the Jamf Pro change management entry or Apple Business Manager audit event for the failed call, even if you are not enrolled in macOS unified logging and iOS sysdiagnose Log Router. The basic 90-day event history works for most diagnostic purposes and lives in the console under Jamf Pro change management log and Apple Business Manager audit log > Event history. Filter by event name (the API action) and time range; the event JSON shows the exact user identity, source IP, request parameters, and error code.
Diff against last known good. The last config change you made is the cause about three quarters of the time, even when the change should not have mattered. Use Jamf inventory history and Time Machine snapshots (or your Terraform / Deployment Manager or Terraform drift report) to see the actual delta between the resource state when it worked and when it broke. The change you remember is often not the only change that happened.
Solution-focused remediation path
If quotas are suspect, the Apple Business Manager Settings > Manage Devices console shows current usage and the active limit side by side. Request increases through Apple Business Manager Settings > Manage Devices, not through Support tickets - quota dashboard requests usually approve faster (often within minutes for soft limits) and they are auditable in Jamf Pro change management log and Apple Business Manager audit log. Set up Apple Business Manager Settings > Manage Devices + Jamf Pro Smart Group + Webhooks at 80 percent usage so you get notified before you hit the wall.
If networking is suspect, use Apple Wireless Diagnostics + Network Utility (or 'networkQuality' on macOS). It is the only tool that simulates the full ENI-to-ENI path including macOS PF firewall, Application Firewall, system extensions, and Content Filter in one call. Manual trace is slower and misses transitive issues. The analyzer charges $0.10 per analysis - cheaper than a 30-minute call with your network team.
If the issue points at IAM, do not start by adding * to a policy. Use macOS Console + Jamf Pro logs + Profile Manager check against the failed action to see the minimum scope. Adding * is the fastest way to fail your next Apple Platform Security review, and it usually does not even fix the issue because the explicit deny is often coming from a higher level (Org Policy, RCP, or permission boundary), not a missing allow.
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.
Wire the fix into an MDM Configuration Profile for self-healing
If the underlying cause is a setting that drifts over time, do not script the fix repeatedly - bake it into a Configuration Profile that the MDM pushes down on every check-in. A Custom Settings payload writes to a specific preference domain; Jamf Pro, Kandji, Mosyle, and Intune all support this. The profile reasserts itself, so even if a user changes the setting locally, the MDM brings it back at the next sync (typically every 4 hours).

</dict>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 Mac Performance and Slow Mac, 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.
Things that bite
A subtle pitfall on Mac Performance and Slow Mac is that the Settings on the device and the SDK can disagree about resource state during a configuration change. Console UI is cached for performance and may show the old config for up to 10 minutes after you change it via API or Deployment Manager or Terraform. Always confirm with describe-* CLI calls during a change window, not with screenshots from the Console.
The other pitfall: assuming that an automated remediation is correct because it succeeded. A Lambda that fires on a Jamf Pro Smart Group + Webhook and runs a remediation step should also publish a metric for every remediation; sudden surges in auto-fix invocations are themselves an outage signal. Otherwise you can hide a slow-burn regression behind a quiet remediation loop for weeks.
Repair sequence
- 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 Mac Performance and Slow Mac 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
mac 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
