Apple Mac OS Update 8.1 for Mac

By Apple Free

Developer's Description

Mac OS 8.1 offers faster Java performance and tighter integration with Internet Explorer. However, you can still use the Web browser of your choice. Mac OS 8.1 supports the new Extended Volume Format for hard disks (also known as HFS+), an option for PowerPC users only. The Extended Volume Format optimizes the storage capacity of large hard disks by decreasing the minimum size of a single file. Existing hard disks formatted with Mac OS Standard Format, including 68K machines, will continue to function in and be supported by Mac OS 8.1. Among the many enhancements and bug fixes offered in this update, PC Exchange and Open Transport have been improved. Be sure to read the included documentation before installing.
