# Installing ESP-IDF on M1 has some quirks. 
Here are some tips.
- make sure to use at least version [4.3.1 ](https://docs.espressif.com/projects/esp-idf/en/v4.3.1/esp32/get-started/index.html#get-started-get-esp-idf)
  - If you are on an M1, the one that was installed from the main docs did not work and ./install.sh will say unsupported architecture
## Troubleshooting

### SSL:CERTIFICATE_VERIFY_FAILED
You might see this error when running the tools setup step. 
```bash
cd ~/esp/esp-idf
./install.sh
```
```bash
WARNING: Download failure <urlopen error [SSL:CERTIFICATE_VERIFY_FAILED] 
certificate verify failed: unable to get local issuer certificate
```

Solution:

You need to run the Python: Install Certificates.command like [this](https://medium.com/@yen.hoang.1904/resolve-issue-ssl-certificate-verify-failed-when-trying-to-open-an-url-with-python-on-macos-46d868b44e10).

### gen_crt_bundle.py: Invalid certificate in cacrt_all.pem
You might see this error when trying to build the hello world example. 
```bash
idf.py build
```

```bash
gen_crt_bundle.py: Invalid certificate in cacrt_all.pem Invalid certificate
```

Solution:

Remove the EC-ACC certificate from the cacrt_all.pem file, like this person, mentions on [github](https://github.com/espressif/esp-idf/issues/5322#issuecomment-931815892).

## Things to remember
- to start using IDF, after creating an alias
```bash
get_idf
```
- you can combine commands
```bash
idf.py -p /dev/cu.usbserial-0001 flash monitor
```
