How to Shrink Massive .git Folders and Clean Broken Packfiles on macOS

Have you ever checked the size of your local Git projects and discovered that a repository is 15 GB, even though the actual source code is only 200 MB? The problem lies inside the hidden .git/ directory.

Git stores every version of every file ever committed. When network drops interrupt a git fetch or git clone, Git often leaves behind massive orphaned packfiles named tmp_pack_* and tmp_idx_* in .git/objects/pack/ that standard Git commands never remove.

How to Compact a Git Repository

To repack loose objects, eliminate unreachable commits, and compress your Git history, navigate into the repository root and run:

git count-objects -v (to see current bloat)
git gc --prune=now --aggressive (to aggressively compress)

Cleaning Orphaned tmp_pack Files

Standard git gc does NOT delete temporary packfiles created during failed operations. MagicMacCleaner's Level 1 Fast Sweep specifically hunts for tmp_pack_* files older than one hour across all your project workspaces and safely cleans them.

Mobile Developer Workflow: Free Up Storage on Physical Test iPhones

While clearing Xcode caches, simulator runtimes, and build containers frees vital space on your Mac, physical iOS test devices rapidly become clogged with test builds, crash artifacts, diagnostic screen recordings, and QA screenshots. Keeping your physical testing hardware lean is essential for rapid on-device debugging and reliable deployment.

• Clearly Smart Storage Cleaner: Compresses gigabyte-heavy bug report screen recordings, detects duplicate test media, and organizes cluttered contacts on development and personal iPhones.
• Swipe Photo Cleaner: Quickly review and purge hundreds of UI test screenshots and demo bursts with effortless swipe-to-delete gestures.
