not able to see my phone on my macbook since one month or so

Hi elias277,

Welcome to Apple Support Communities. There are steps we recommend for you to follow that can help your Mac detect your iPhone. Our recommendation is to follow these steps:

1. Look in the Finder or iTunes

On a Mac with macOS Catalina or later, look for your device in the sidebar of any window in the Finder.*

On a Mac with an earlier version of macOS, look for your device in iTunes.

On a PC with iTunes for Windows, look for your device in iTunes.

2. Update the software on all devices

Update your iPhone or iPad

Update your Mac

Update your Windows PC

On your PC you might also need to update iTunes and update drivers.

3. Connect your device directly to your computer

Make sure that your device is unlocked and showing its Home Screen, then use a USB cable to connect it directly to your computer. Don't connect to a USB hub, display, or other device. 

If that doesn't help, disconnect your device and all other USB devices and accessories from your computer. Then reconnect only your device. 

4. Trust your computer, if asked

If you see a “Trust this Computer?” alert on your device when you plug it into your computer, tap Trust.

5. Allow the accessory to connect

When connecting your device to a Mac laptop computer with Apple silicon, your Mac might ask whether you want to allow this accessory to connect. If so, allow it to connect.

6. Restart your devices

Restart your iPhone

Restart your iPad

Restart your Mac

Restart your Windows PC

7. Try a different port, cable, or computer

The issue could be related to your computer, its USB port, or the USB cable connecting it to your device. If possible, try a different computer, USB port, or USB cable. Also check for any debris in the charging port on the bottom of your iPhone or iPad.
