Lack of storage after migrating from iMac to MacBook

I recently transferred files from my iMac to a new MacBook Pro 14" 2021 16GB Ram, 1TB SSD. My iMac had a 1TB SSD, with two 500GB partitions, MacOS and Bootcamp. I still had roughly 200GB free on both partitions.

I used a Time Machine backup to copy my files to my MacBook, and I now only have 160GB spare. Where has the other 700GB (Size of Bootcamp partition plus the 200GB free on my MacOS partition) gone, and why? I have deleted all the apps I don't use, which made no difference to the available space left. About This Mac/Storage shows I have 163GB of System Data (I've deleted all my cache files), 488GB of documents (should less than ½ that), 85GB of Music, 38GB of Apps, 25 GB IOS files, 15GB MacOS files, and 10GB Developer files.

Any help in solving would be greatly appreciated.

Hello mark_1.


Thank you for using Apple Support Communities. If you're noticing storage discrepancies with your MacBook Pro, we can recommend a couple of steps you can try to see if that helps sort this issue out. First, try repairing your disk to see if that show any positive affect with your storage properly displaying: How to repair a Mac disk with Disk Utility - Apple Support


1.) Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
Apple silicon: Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.
Intel processor: Turn on your Mac, then immediately press and hold these two keys until you see an Apple logo or other image: Command (⌘) and R.
2.) You may be asked to select a user you know the password for. Select the user, then click Next and enter their administrator password.
3.) From the utilities window in macOS Recovery, select Disk Utility and click Continue.
For each disk that you're repairing, start by selecting the last volume on that disk, then click the First Aid button  or tab.
Click Run to begin checking the selected volume for errors.
-If there is no Run button, click the Repair Disk button instead.
-If the button is dimmed and you can't click it, skip this step for the disk, container, or volume you selected.
-If you're asked for a password to unlock the disk, enter your administrator password.
After Disk Utility is done checking the volume, select the next item above it in the sidebar, then run First Aid again. Keep moving up the list, running First Aid for each volume on the disk, then each container on the disk, then finally the disk itself. 

You can also try to reindexing your files. This can sometimes help fix storage issues. For steps click here: Rebuild the Spotlight index on your Mac - Apple Support


Depending on how much data you have, this step can take several moments to complete. Feel free to keep us posted. Best of luck.
