iATKOS | United Kingdom

I have a Hackintosh with the specs mentioned below

Intel Core i5-4440

Asus H81-MCS

8 GB Kingston 1600Mhz DDR3

120 GB WD green SSD

Sapphire RX 460 4GB ( dual fan variant )

And a 500W PSU

Now, Initially Mac OS booted in 20s and everything was fine
But after a few months, and some Mac OS updates, it takes almost 2 minutes to boot
I can't seem to find any forms that might help me
Please suggest some fix to this
