1. First of all, not many companies use Macs. Very rarely they do. Especially in Northern and Central Europe.
2. Almost all of the servers we have (over 10,000) run on Windows
3. Apple doesn't have any enterprise software. What is something that's equivalent to Azure? Nothing.
4. Despite very small percentage of users using a Mac we have so many tickets opened about Macs. Today 15 tickets were open, the last one being "Microphone doesn't work on a Mac" + Addigy is extremely uncomfortable to use.
5. If Windows was bad it wouldn't be so mainstream. macOS is only used by 5% of the world (15% if we count desktop only operating systems)
6. Doesn't change the fact that older PCs are more usable and receiving security updates for far longer than Apple's macOS. Compare macOS how usable is OS X El Capitan (which dropped many Macs) to Windows 10 these days and which OS is more secure.
1. You're right to a point in the old stodgy world of legacy companies who are on old systems but have you seen what modern tech companies use ? Google, Facebook, Twitter etc. They're overwhelmingly Mac shops and they praise how Macs simplify their security headaches and bring them less virus, trojan problems.
2. I work at a university and almost all our servers are Linux (around 1000) - we ALWAYS try to avoid a Windows server and in 95% of cases we can (even though for our university, the licensing is essentially unlimited).
3. Of course Apple has enterprise software, lots of it, just not exactly what you need.
4. Mac are notoriously simpler and more reliable machines, fine you get some tickets about Macs but that's just your unique scenario. Windows 11 still has its old; horrific Control Panel with seven Windows for accessing microphone options. Please don't tell me that Windows does this better than Mac when Microsoft rely exclusively on third parties for ALL of their hardware needs.
5. Windows was there first, it's very powerful lobbying made it a mainstay and it CAN be a lot cheaper than Mac initially, regardless of the fact that in the long term there's a good chance that poor quality Windows machines cost more in replacements, reinstalls and user headaches than just buying a MacBook in the first place.
6. This is about the only place I agree and disagree with you at the same time. You're right that Apple could continue to release security updates to older machines, probably without much of a performance impact as security updates are not typically monolithic architecture rebuilds (however in some cases they are), they're often just simple changes to code which address poorly though out data movements in memory and CPU treatment. However for Apple OS and hardware advancements are tied tightly to their business model - when they release a new OS they typically release new hardware and no doubt they want sales of this hardware hence pushing people generally in the direction of new sales is their model - am I in agreement with this, no, but its how most companies operate and it wont change tomorrow. Now, finally, please prove to me which OS is more secure because one seems to get more updates. There's absolutely NO correlation. A more insecure machine may receive more updates because they've more problems to fix, a more secure OS may receive less because its already relatively secure or the success in exploiting something is more complex due to other security factors. Please stay out of this discussion as I don't get the impression that you know what you're talking about. Windows machines by default make everyone an admin with nothing more than an UAC "Ok" to stop them doing something stupid (something they see so many times per day that clicking OK is just instinctual and provides little security). Macs still prevent major system changes behind a user password entry which is very rare meaning the user will think twice before giving it. Macs are also built on a fundamentally security from the ground up approach of a Unix system with security as first principals. Windows was a disaster from the ground up "security system" from its inception. Please DO NOT compare these systems from a security point of view.
