iCab is my main browser on Mac OS 9, Mac OS X, iPhone and iPad.
I have used iCab since late 1990’s when I got my first Macintosh. After some time with Netscape I found a light browser from a German developer and I was impressed. This tiny browser has got all the options you can think of and lots of powerful tools, a download manager where if you mess things could end downloading the whole Internet LOL, a cookie manager, a form manager, an incredible powerful filter manager, on which you can do the magic of iCab, a cache browser, a Kiosk mode that made it the browser of choice on the Spanish ‘Ciutat de les arts y les ciències’ at Valencia
http://www.cac.es/?languageId=1 on their iMacs and eMacs, a powerful find tool, a HTML validator, etc … all built-in, without any add-ons that made your browser work as a percolator!!
And don’t forget that the latest version for Classic, 3.0.5 is not even optimized for speed, as Alexander was working on turning the Carbon iCab into the Cocoa WebKit version that 4.0 was.
Some other accolades of iCab were.. it’s the only browser with Tabs for 68K Macintoshes, the first browser to get a 100/100 on Acid3 test, the fastest browser on Mac OS X (tested on 2008)
I doubt that Alexander keeps a classic Macintosh nowadays to develop for Mac OS 9. I know he is super busy with the iOS version of iCab Mobile, he updated iCab Mac OS X for El Capitan some days ago.
And of course iCab is for Macintosh only, not a thing from another place, a foul, alien and misshapen troll lurking under the bridge named /Applications.
In fact I asked him some time ago if it was plausible an iCab version for SGI as there the modern browsers available are, umm, firefox 3 only. But he told me that probably the only option to see iCab on SGI machines would be running the SGI Freeware Basilisk II Emulator.
And about Alexander, he replies your enquirers on a daily basis. His Apps, mainly iCab Mobile are his only income, so don’t be a pirate. He has other great apps, but mostly unknown out of Germany, yes, that still happens in the All-Connected Internet era.
