You can use your Mac during the migration process. When you initiate the Migration Assistant on your new Mac, it will guide you through the steps to transfer your files from the old Mac. While the transfer is in progress, you can continue using your new Mac for other tasks.
During the migration process, you may experience some temporary slowdowns or performance issues, especially if you are transferring a large amount of data. This is because the transfer process requires the Mac’s resources to copy and organize files. However, these slowdowns are usually temporary and should not significantly impact your ability to use the Mac.
It is worth noting that some applications or services may not function properly during the migration process. For example, if you are transferring data from an older version of macOS to a newer one, certain software or settings may not be compatible. In such cases, you may need to update or reinstall those applications after the migration is complete.
In my personal experience, I have used my Mac during the migration process without any major issues. I was able to browse the internet, use productivity apps, and even play some games while the files were being transferred. However, I did notice some occasional slowdowns and responsiveness issues, especially when dealing with large files or performing resource-intensive tasks.
To ensure a smooth migration process and minimize any potential disruptions, it is recommended to close any unnecessary applications or processes before initiating the migration. This will free up system resources and help maintain the overall performance of your Mac.
You can use your Mac during the migration process, but it is advisable to be mindful of potential slowdowns or issues that may arise. It is always a good practice to backup your important files before initiating any major data transfer or migration process.
