is it safe to charge my iphone xs max from my imac?

Keep in mind if you have your mac set to sleep the computer will stop charging the iPhone when it goes to sleep.

Hi AliAbbas7777,

Thank you for posting here in Apple Support Communities. We see that you're wanting to know if it's safe to charge your iPhone with your iMac. Great question! Yes, it is definitely safe to charge your iPhone with your iMac. However, for the best results, we recommend that you use a USB 2.0 or a USB 3.0 port, and not a USB hub or your keyboard.

If you're experiencing issues charging your iPhone with your iMac, we ask that you check out the troubleshooting steps here: If your iPhone or iPod touch won't charge

Take care!
