rdmsm4x-changelog-20260912-1347-xcode27rc-and-memory-audit
Xcode 27.0 RC (27A266a) installed and selected on rdmsm4x; Tyrell daemon restarted after a memory audit that found no active leak. 2026-09-12 13:47:05 EDT, claude@rdmsm4x/rtty-c0.
Xcode 27 RC
- Source: ~/Downloads/Xcode_27_Release_Candidate.xip on rdmbair15m5 (2,014,229,334 bytes, saved 2026-09-12 03:09); copied to rdmsm4x:~/Archive/xcode-staging-20260831/ (size verified; xip signature check on expand).
- Installed as /Applications/Xcode-27.0-RC.app (same name as on
rdmbair13m5 and rdmbair15m5, which already had it selected);
xcode-select -s,xcodebuild -license accept,xcodebuild -runFirstLaunch→ Install Succeeded.xcodebuild -version= Xcode 27.0 Build 27A266a; Swift 6.4. - Kept, not deleted: /Applications/Xcode-27.0.0-beta.6.app (previous selection, 27A5252f) and /Applications/Xcode.app (26.6, used by the RTTy Standard archive lane). Remove beta 6 when convenient.
- Not installed on rdmpw3265m / rdmpw3275m: the RC's Xcode binary is
arm64-only (
lipo -archson the Air's copy), so the Intel Mac Pros stay on Xcode 26.6 despite the RC's macOS 26.6 minimum. jdmbair13m5 was powered off. - Undo:
sudo xcode-select -s /Applications/Xcode-27.0.0-beta.6.app.
Memory audit (128 GB host, ~9 GB free, ~64 GB inactive cache — not under pressure)
- No process grew over a 90 s two-sample window (claude sessions, codex, OrbStack, Dropbox, Chrome, Claude.app, Gemini, Spotlight/QuickLook agents all flat).
- Largest: OrbStack VM 4.8 GB (serves Docker for dev.ecs0.net; left
alone); tyrelld --server 2.46 GB after 14 h (restarted via
launchctl kickstart -k gui/501/com.eastcoastscience.tyrelld; back at 1.7 GB within 6 s, so ~2.4 GB is its resident index, not a leak — cf. ISSUE-20260904-01 which was 14–17 GB); DropboxFileProvider 775 MB (stable; left); QuickLook ThumbnailsAgent 549 MB (system-protected, kill ignored; left); media-indexer 484 MB + AMPLibraryAgent 438 MB (Photos/Music indexing that started 05:25; left). - Terminal: Rich closed the idle tabs himself; the remaining ttys each host a claude/codex session.
