Mac 7.5.5 Software
Need a copy of System 6.0.8, 7.0.1, or a newer version of the Classic Mac OS for your vintage Mac? You can dig through apple.com and try to find them – or you can download them using the updated links on this page. (Apple does rearrange things, making it more difficult to find things.) All versions of the Mac OS linked here are copyrighted by Apple Computer and free to Macintosh owners. System 7.1.x as well as 7.6.x and later are not free products and must be purchased.
Making Floppies
QuickTime 5 was one of the shortest-lived versions of QuickTime, released in April 2001 and superseded by QuickTime 6 a little over a year later. This version was the last to have greater capabilities under Mac OS 9 than under Mac OS X, and the last version of QuickTime to support Mac OS versions 7.5.5 through 8.5.1 on a PowerPC Mac and Windows 95.
Software is stuffed and requires an expander, such as StuffIt Expander (which was traditionally bundled with early Mac web browsers). Mounting disk images or making floppies from them requires Disk Copy (download Disk Copy) or MountImage.
You will need a 400K or 800K floppy drive to produce single-sided disks for use with the Mac 128K and 512K Fat Mac. Apple’s high density floppy drives cannot format single-sided floppies.
You cannot use a USB floppy drive to create 800K floppy disks; they can only be formatted and written to using an Apple 800K or 1.4M HD floppy drive.
You should have no trouble formatting and writing to high density floppies using a USB floppy drive.
Drive Prep
Whenever possible, Apple branded hard drives should be formatted or updated with HD SC Setup 7.3.5 or later before installing a new version of the OS. (Exception: If the hard drive of a Mac Portable is formatted with any version newer than 7.3.1, it will crash instead of waking from sleep mode.)

Why can’t we simply put a passcode or touch ID or FaceID to the apps we want to lock?Even didn’t have much to offer until recently. But then it doesn’t exactly lock the app but completely hides it, which is a bit annoying. Password protect mail app mac computer.

Developer Nick Lee this evening has shared a video showing how he managed to hack an Apple Watch to run Macintosh OS, System 7.5.5. For those counting, that was released 19 years ago on September 27, 1996. The Apple Watch was released April 24, 2015. That’s a pretty impressive feat by Lee (via MacRumors).
Lee was able to accomplish this with an Apple Watch running watchOS 2 and the Mini vMac Macintosh Emulator. The mini vMac Macintosh Emulator is designed to allow more modern devices run software that was designed for early Macintosh computers. Macintosh OS, System 7.5.5 was designed to run on a PowerPC Mac at the time of release.
Mac software to combine videos online. These four main functions are used to convert video, burn your homemade videos to professional DVD, download videos from internet and convert the videos at the same time, and it can also be served as a media server to project videos from Mac to your TV. To combine videos, we only need to use the first function CONVERT.
