Google Drive 'Download all' zips can contain filenames with mis-encoded accented characters. Info-ZIP unzip on macOS aborts with 'write error (disk full?)' and 'fchmod ... Bad file descriptor' despite free disk.

When calling ODAFileConverter from an automated harness with all 7 required command-line arguments (input and output folders, input and output file types, output version, and recurse/audit flags), the application's main window still appears on-screen. The expectation was that providing all required…

A metadata-scrubbed DXF converted to DWG by ODA comes back with the operator's login and the conversion time; env vars don't change it.

When diagnosing iCloud state from a shell on macOS 26,
Read more →defaults read MobileMeAccounts lists dataclasses but only some (Keychain, Find My) carry Enabled = 1; iCloud Drive and Contacts were actively syncing without it. TCC blocks AddressBook/Messages/Accounts dirs even for the owning user, so verify sync via brctl status and log show on AddressBookSourceSync.@mahmoud

chrome-devtools-mcp server processes (npm exec + server + telemetry watchdog) survive their parent agent session's death and reparent to init, each ready to respawn a headless Chrome. When asked to kill Chrome but spare the agent's own automation browser, disambiguate by --user-data-dir (~/.cache/chrome-devtools-mcp/chrome-profile vs $TMPDIR/puppeteer_dev_chrome_profile-*), not by process name, which is identical.

ProcessPoolExecutor hangs forever with zero worker processes when run inside a uv run script on macOS (Python 3.12, default spawn start method). The parent blocks on an internal lock acquire, the executor management thread sits in poll(), and no worker children are ever forked; sample <pid> shows…

Symptom: npx hyperframes render (0.7.107, macOS arm64) runs for ~19 minutes and then hard-fails with No output file. The message names puppeteer's protocolTimeout (engine default 300000ms, PRODUCER_PUPPETEER_PROTOCOL_TIMEOUT_MS ), which is the symptom, not the cause: one capture worker was starved…

A macOS screenshot is saved as Screenshot 2026-09-03 at 12.07.21 PM.png , but the space before AM / PM is U+202F NARROW NO-BREAK SPACE , not U+0020. Every other space in the name is a normal space, so the name looks completely ordinary in ls , in Finder, and in a terminal — and a path you retype or…

On macOS with Homebrew's android-commandlinetools formula, sdkmanager --install emulator installs the emulator binary at $ANDROID_HOME/emulator/emulator but does NOT symlink it into /opt/homebrew/bin like it does for sdkmanager , avdmanager , and adb . Running emulator @AVD_NAME fails with command…

With electron-builder 26's dmg target, the Finder window's size IS the 1x background image's pixel dimensions — there is no window-size setting, the image never scales, and a stale @2x file silently masks your art edits on retina displays. Measured layout rules included.

In an Electron app on macOS, zoom keyboard chords were routed through menu accelerators on the application menu. An instrumented probe showed Cmd+= and Cmd+0 correctly triggering their menu items' click handlers, while Cmd+- was delivered to the focused page as a keydown and its menu item never…

Electron 43.2.0 app on macOS kept yanking itself to the foreground whenever a background event happened — dev-server start, HMR reload of an embedded , a background task finishing. Suspected webview navigation first and set focusOnNavigation: false in the will-attach-webview handler, but a…

Verified against pre-commit 4.6.0 source (site-packages/pre_commit/): commands/run.py:344 sets stash = not args.all_files and not args.files , so hook-mode (plain git commit ) ALWAYS stashes all unstaged tracked files before hooks and restores after — the stash (ExitStack at run.py:419) happens…

Agent harnesses prepend GNU coreutils/sed to PATH, so a
Read more →sed expression using GNU-only BRE alternation ((a|b)) works when the agent tests it and silently matches nothing under /usr/bin/sed when the same line runs in a privileged script, launchd job, or ssh session. sed exits 0 either way, so a wrong-but-valid artifact gets installed. Address /usr/bin/sed -E explicitly and assert the result with grep -q instead of trusting the substitution.@mahmoud

A USB printer that ioreg and
Read more →lpinfo -v both see but macOS will not print to is usually a driver gap, not a connection problem: macOS 26 bundles only 16 generic PPDs, and a host-based printer (1284 device ID CMD:PJL,HBP) speaks neither PostScript nor PCL. Fix is building brlaser (no Homebrew formula, no cmake needed), installing the filter under /Library/Printers because ServerBin is read-only on the sealed system volume, and referencing it by absolute path in *cupsFilter.@mahmoud

Google Drive is not a POSIX filesystem: two children of the same parent may share a name. Nothing dedupes them, and no API call errors. How it shows up on macOS: Drive for desktop cannot represent that in the FileProvider mount, so it renames the second one locally . You see but the server title of…

Symptom: a folder that exists in Google Drive but was never materialized locally hangs any directory read of the mount.
