How to Split Screen on Mac
TL;DR:
Using Split Screen on Mac for multitasking and side-by-side windows requires configuring built-in macOS settings, verifying account permissions, and ensuring adequate storage or sync status before arranging your layout.
● Run a small layout test before proceeding to prevent data loss, ensuring you keep your original Mac files or current backups completely unchanged until the final result is verified.
● If the workflow stops midway or output looks incorrect, resolve the issue by charging devices, freeing space, or adjusting mismatched compression, permissions, or metadata settings one at a time.
● Apply Wondershare Repairit to fix corrupted or unreadable local Mac and GoPro files, including photos, videos, documents, audio, or emails, before attempting further edits, transfers, or archiving.

Steps
-
Step 1
Check the device, account, connection, permissions, and available storage before starting.

Open the relevant GoPro app, Finder, System Settings, Photos, Screenshot, or sharing control.
-
Step 3
Apply the needed setting or select the files, window, screen area, or device to use.
-
Step 4
Run a small test and confirm that the output, connection, layout, or transfer behaves as expected.
-
Step 5
Save or move the result to a clear destination and keep the original file or setting available.
Common Issues and Fixes
- The source file will not open: the file may be incomplete, unsupported, interrupted, or corrupted; copy from original storage, use a compatible tool, or repair the damaged file.
- Output or playback looks wrong: settings, compression, permissions, metadata, or device compatibility do not match; adjust one setting at a time and compare a test result.
- Process stops midway: battery, storage, sync, connection, or source-file errors interrupted the workflow; charge devices, free space, reconnect, and retry from a clean source.
- The result is hard to verify: preview data, thumbnails, cloud placeholders, or app caches hide the final state; open the result in a separate viewer or test device.
Quick Tips
- Keep the original Mac file or backup unchanged until the result is checked.
- Avoid deleting unknown system files or changing permissions without a verified recovery path.
- Use built-in macOS tools for sensitive files unless an online service is approved.
- Repairit is relevant when local photos, videos, documents, audio, or email files become corrupted or unreadable.
