I have a Mac OS X but I know Mac OS is a computer made by the brand/company, Apple.
Unfortunately No. You should upgrade your OS 9 machine to OS X
Most USB portable speakers are compatible with the Mac OS, but you should make sure that the speakers have Mac Drivers, otherwise they will not work properly.
You cannot without erasing your hard drive and installing Mac OS 9 from scratch. Even then Mac OS 9 may not run on modern Mac hardware because Mac OS 9 needs the ROM chip to boot. Modern Mac OS X hardware uses EFI to boot the system instead of a ROM chip to boot. Mac OS X v10.0 - Mac OS X v10.4 support Mac OS 9 applications and can run them, you just need to install the Mac OS 9 compatibility program which can be found on the Mac OS X Install CD.
The second name of Mac OS X v10.4.5 is Mac OS X v10.4 Intel.Mac OS X 10.4 was known as Mac OS X Tiger.
It is very easy to install MySQL directly onto the Mac OS X. MySQL can be downloaded onto the Mac OS X. When the download is complete, the folder should be opened and the executable should be launched. From there, just follow the prompts to install.
If you have a Mac, it should already come up. If you don't, I have no clue!
The oldest mac OS is System 1
Mac OS Leopard
Mac OS X 10.4 (Tiger) needs to be purchased as it is not possible to update from Mac OS X 10.2.8
Unless the disc is damaged and so needs reformatting you can run the Mac OS installer over an existing Mac OS.
Mac OS X is an operating system released by Apple Inc. It is designed for Apple branded computers, which is why you will never see a Dell, or an HP computer run Mac OS X. There are only two important versions of Mac OS X, Mac OS X Server, and regular Mac OS X. Mac OS X server was designed for servers, while regular Mac OS X was designed for most computers. The current version of Mac OS X (10.6) is named Snow Leopard.
