Note:

PowerMac, PowerPC, eMac, iMac PPC, iBook (Apple recycled the name iBook for its eBook application on new Macs and iOS devices), Powerbook, Classic all refer to Macs that are older than the present series

of Macs. Posting in those forums about a current Mac, shows you have not researched your Mac sufficiently to get a succinct answer to your query. Apple menu -> About This Mac will tell you the Mac OS version or System version you are running. The X in the version is important, and so is the preceding 10 in the version if it exists.

Questions saying X.1 could refer to Mac OS X 10.13.1, 10.1. Don't truncate the version you see.

There are no iOS forums specific to the operating system found on iPads, iPod Touch, AppleTV, Apple Watch, and iPhones. Figure out the type of portable device you are running to ask a question about that device specifically.

Apple has these identifying articles as well:
