Problems on my new Mac after using Migration Assitant

I used Migration Assistant to copy data from my old iMac (21.5 Inch, Mid 2011) running macOS High Sierra, Version 10.13.6 to my new iMac (Retina 5K, 27-inch, 2020) running macOS Sonoma 14.4.1. The transfer seemed to work OK but when checking the HD information I see that "everyone" is set to "Read only". I am an Administrator and have unlocked the padlock using my password but if I try and change the permissions for "everyone" I get the message "The operation can't be completed because you don't have the necessary permission". As a result I cannot move, delete, create or download any files. Can anyone help please? Thanks.

iMac, OS X 10.11

Too bad you did not post here prior to using MA. I would recommend doing an erase and install and following the instructions below!!!!!!

· Always connect your old Mac's Time Machine External Hard Disk prior to startup then it will be dead simple to migrate from your old Mac's Time Machine backup!!!! When you start the new Mac for the first time it will startup Setup Assistant (SA), SA will get to a point where it asks if you are migrating from another computer, select Yes and follow the on-screen prompts and it's done! This is the easiest, quickest and most reliable method to migrate from the old Mac to the new Mac is to simply connect the old Mac's Time Machine External Hard Disk to the new Mac using a USB cable before you turn on the new Mac.

· NOTE 1: You will likely need a USB A to USB C adapter, you can find them on Amazon for $10 or less.

· NOTE 2: If you have already done SA on the new computer then simply connect the Time Machine External Hard Disk using a USB cable and launch Migration Assistant (MA) which is located in Applications - Utilities - MA. Then follow the on-screen prompts.

· The ONLY difference between MA and SA is MA will create a new user account that you need to log into.

Both SA and MA migrate applications (not 32 bit apps), data files & settings. They do not migrate Mac OS itself. Some professional apps such as Adobe and Microsoft apps may require re-installing their apps as they will not allow them to be migrated. As long as you kept the security keys for installing their apps, it is not an issue.

Finally, never EVER use Wi-Fi when doing Setup Assistant or Migration Assistant. Why, it simply fails in most cases. Please read and follow the directions in Setup Assistant and Migration Assistant. If you do not have a Time Machine backup of the older Mac then create one! If you are not aware of Time Machine, please read Back up your Mac with Time Machine and finally if you need an External Hard Disk to use as a Time Machine External Hard Disk then many experience users on these forums prefer the OWC Mercury Elite Pro due to it's reasonable price, high level of quality and ease of use.
