Thanks God for you developers out there! I am still working and using my old metal gray G5 - PPC, I am running OS X 10.5.8 and thank God someone thought of us when building this most recent version of SAFARI WebKit! Thank you so very much!!) Well I was excited until today when I tied to go to this webpage (support.apple.com/kb/dl170), It said "SAFARI CAN NOT OPEN THIS PAGE" using the latest Safari webkit downloaded from here. Luckily i still have TenFourFox and it loaded that webpage and downloaded the update file that I needed with no problems. Looks like I am still stuck on the old slow hog TenFourFox but at least it will still load the plain old Internet!! It is really sow on my old Mac.))

Can report that 604.5.6_2 provides amazing performance for Youtube playback on my 1.33Ghz iBook - 360P video at less than 70% CPU! Note - you do need to use Quicktime 7.7 without it Youtube is still just a slideshow.

I wish most projects were as dedicated... :)

Great browser for old PowerPC Macs. This browser is among few valid alternatives for our machines now in 2017. It is fast, it is updated! I can surf the web without stressing too much my cpu, I can even watch videos on facebook and Youtube smoothly! Unbelievable on a MDD G4 1.25 Ghz in 2017. Thank you for bringing us your work :)
