Why won't your Mac let you upload files to your browser?

Lots of users are asking why won't my Mac let me upload files to my browser? Although frustrating, it's a known glitch and one that can be fixed relatively quickly.

We've put together some simple steps to help you solve this issue — let's go.

Why can't I upload files on my Mac?

Like with many Apple bugs and glitches, there are many causes: when the upload button stops working on your Mac, it's likely caused by a recent software or app update, corrupt browser preferences, or caching issues.

Follow the steps below to fix it.

1. Quick fix: Run a smart scan

One quick way to fix issues like when your MacBook won't let you upload files is to utilize the in-depth strength of an Apple notarized Mac app like CleanMyMac — it can clear up browser cache and other junk, update apps (including third-party browsers), and run maintenance tasks. All of these can directly solve the glitch.

Besides, CleanMyMac can detect Mac-specific threats and help you declutter your MacBook by uninstalling apps and removing duplicates and similar images. These won't fix the upload issue, but they will generally make your Mac snappier. 

Here's how to use it:

1. Open CleanMyMac — get your free trial here (you can test it for 7 days first).
2. Choose Smart Care in the sidebar > Scan.
3. Click Run to launch recommended maintenance routines, clean up junk, and complete other tasks. 

Additionally, check out the Cleanup feature to get rid of browser cache and the Protection feature to remove browser-specific cookies, search history, and other browser data. 

Why use CleanMyMac

• Comes with 25+ tools to clean, protect, and maintain your Mac
• Blazing fast and easy-to-use — a Smart Care scan takes, on average, 52 seconds, and running the tasks takes 85 seconds more
• With the help of the Cleanup feature, users find and remove, on average 10.5 GB of safe-to-delete junk files (including browser cache)

2. Make sure your browser is up-to-date

Ensuring your browser software is up-to-date is essential for keeping glitches like this at bay.

Safari

When you update your macOS, this will update your Safari browser. Here's a reminder of how to update macOS:

1. Main Apple menu > System Settings > General > Software Update.
2. Click Update Now or Restart Now and follow the on-screen instructions.

Chrome

To update Google Chrome, you will need to check its settings. 

1. Open Chrome, click Google Chrome main menu > Settings > About Chrome.
2. Check here for available updates.

3. Check your Disk Access preferences

Accidentally disabling your browser's full disk access will not let you upload docs, so check the permissions in System Settings. Here's how:

1. Go to the main Apple menu > System Settings > Privacy & Security > Full Disk Access.

2. Toggle on your browsers.

3. Restart your browser and try again.

You should now be back up and running.
