Recover files from a Pixel 2 stuck in bootloop My Pixel 2 is stuck in the boot loop. I will send it for a replacement but I would like to recover some files that weren't backed up in the cloud. 

I can see the phone using adb devices and I was hoping to use the abd pull command but I can't due to permissions. I am using a Mac and my phone is not rooted.

adb shell ls -lah

Is it possible to pull all files from the phone or mount it on my Mac? I'm only interested in the pictures really.
I have used ADB on a Mac before, so it should be possible. I would suggest trying to pull specifically the emulated SD partition using the full path shown by your ls command: adb pull /storage/self/primary

I have seen a variety of "real paths" across different phones/versions of Android. Its actual location may be in emulated or mnt.

If it is stuck in a loop and never booting to Android, then there is little ADB can do.
