맥 os 업데이트 이후에 사진이 자꾸 깨집니다

Hi 보람이94119797,

Sorry that images in Photoshop appear broken while using the Liquify tool. 

After you use the Liquify filter on an image on a specific Mac hardware/graphics cards, there are unexpected black pixels on the image.

Macs with the following graphics cards are affected:

AMD FirePro D300 2048MB

AMD Radeon HD - FirePro D500

AMD Radeon R9 M370X 2048 MB

Workarounds:

Hold down the Option key when you select Filter > Liquify to disable the Use Graphics Processor option when launching the Liquify dialog

• Disable the Use Graphics Processor option in the preferences.
• Choose Photoshop > Preferences > Performance.
• Deselect Use Graphics Processor.
• Quit and relaunch Photoshop.

Thanks,

Akash
