Recently, because of limit of memory, my macbook will run slowly when I open several applications, coding, and do some paperwork at the same time. Thus, I bought a new macbook pro 2021 - M1 chip. However, there are lots of data need to migrate to the new macbook. And there are some difference between m1 and intel chip. This blogs give some hints for migration between the computer.
1. Erase the old computer
Backup using time machine
Sign out of iCloud
If using macOS Catalina or later, choose Apple menu > System Preferences, then click Apple ID. Select Overview in the sidebar, then click Sign Out.
If using an earlier version of macOS, choose Apple menu > System Preferences, click iCloud, then click Sign Out.
You will be asked whether to keep a copy of your iCloud data on this Mac. You can keep a copy, because you’re erasing your Mac later. Your iCloud data remains in iCloud and on any other devices that are signed in to iCloud with your Apple ID.
Sign out of iMessage
Open the Messages app, then choose Messages > Preferences from the menu bar. Click iMessage, then click Sign Out.
Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R. Release the keys after about 20 seconds. This clears user settings from memory and restores certain security features that might have been altered
Erase your Mac and reinstall macOS
Follow the steps to erase your Mac and reinstall macOS. After macOS installation is complete, your Mac restarts to a setup assistant. To leave the Mac in an out-of-box state, press Command-Q to shut down instead of continuing setup.
remember!! this step can combine together. In the UI of erasing the computer, after erasing you can go back and install your new computer!! do not close the computer. Open the recovery tool in a erased computer may have some unexpected problem
2. Some application may have conflict for mac m1 and intel
- for the arm brew, we shall use /opt/homebrew/bin/brew
- for the arch 64 brew we shall use
arch -x86_64 brew - after data migration, some application or binary file may lose effect. Please check:
- each Application,
- Cellar,
- binary file and
- all links in the .bashrc, bash_profile to check the functionality of these commands
- we cannot use intel simd AVX/SSE anymore in mac m1
- zsh move the cursor to the head or end command + <-,->
- TensorFlow need to use the special version of MacBook M1
- The Apple M1 can connect to at most FIVE monitor
- TBC…
Overall, through an experience of a year of using MacBook2021 M1 Chip (Even though M2 chimp has been released)
3. Update to MacOS Ventura
- Through the recent usage experience, everything is perfectly good.
