New EOS 6D Mark II Camera - Cannot import photos

[Melissa219341583n7m]

I purchased a new Canon EOS 6D Mark II camera this month NOV 21 alongside with a San Disk Extreme Pro 64GB is the new SDXC Card that came with it. I updated my photoshop versions to 23.0.2 Release so its the 2022 version. I formatted the SD Card in my camera as well. My problem is I can easily take photos in JPEG format and when I insert the SD card into my IMAC version 11.6 the folder for the SD card shows in the locations when I click on it, it quickly shows then dissapears - so nothing shows. When I eject SD card and try again it sometimes previews the images allowing me to click on 1 but then crashes and says error. 

I cannot seem to figure what the problem is? Is it the camera or SD card . This SD card is recommend for this camera. 

Thanks
