Niresh Catalina on Dell Inspiron 5491

Recommended Posts


Hi Guys,

Yesterday I installed Niresh Catalina on my Dell Inspiron 5491.


10th Generation Intel Core i5.

Graphics:Intel UHD Graphics 620 and NVIDIA GeForce MX 230.


512 GB Nvm e SSD

Audio:Realtek ALC3271.

Now, the graphics card is not shown in About This Mac and Sound is not working.

Any help will be appreciated.

Please help me.

Thank you.
