DISCUSSION

1) Question: What is System 7.5.3 Revision 2?

Answer: System 7.5.3 Revision 2 is a set of system software enhancements that improves the reliability and performance for the computers mentioned in a later question. The objective of this update is to quickly respond to bugs and deliver them on one disk, small enough where most people will want to obtain it electronically (through the Internet or on on-line services). The fixes it provides will be incorporated into an upcoming reference release of System 7.5.3. This update is the first of a series of rapid response updates for System 7.5.x that will be released prior to Mac OS 8.

2) Question: When will it be available?

Answer: Apple plans to announce Macintosh System 7.5.3 Revision 2 on June 7, 1996. It will be available online via the following Apple Internet sites:

ftp.support.apple.com
ftp.info.apple.com
http://www.support.apple.com
http://www.info.apple.com

and Apple Computer Higher Education gopher server at info.hed.apple.com.

The update also will be posted on several online services including:

AppleLink
America Online
CompuServe

Customers who do not have access to an online service or the Internet can order the update on two floppy disks in the U.S. for a $13 shipping and handling fee. The number to call in the United States to order the update is 1-800-293-6617, ext. 1198. The number to call in Canada to order the update is 1-800-361-6075. The update will also be incorporated in the upcoming reference release of Mac OS 7.5.3 (Unity).

3) Question: Why is it called 'Revision 2'?

Answer: Apple has decided to call this product System 7.5.3 Revision 2 and not use the term "update" for two reasons:

• Revision 2 will provide improvements only for specific computers running the current system software version, which is different from all other updates Apple has released in the past.
• In addition, Apple wanted to avoid confusion with other current system software update type of products from Apple.

Apple selected the "2" in "Revision 2" since it already has released two minor versions of System 7.5 version 7.5.3. After installing System 7.5.3 Revision 2, all systems running System 7.5 version 7.5.3 will have all of the most current system improvements.

4) Question: Do I still need to install System 7.5 Update 2.0?

Answer: Apple released System 7.5 Update 2.0 two months ago, and still is recommending that customers using pre-7.5.3 versions of System 7.5 install it if they have not already.

5) Question: Does Macintosh System 7.5.3 Revision 2 contain the 'Important Software Updates' included with PCI Power Macintosh systems?

Answer: No. You should install these in addition to the Macintosh System 7.5.3 Revision 2 update.

6) Question: Who should install System 7.5.3 Revision 2?

Answer: Apple is recommending that only customers with specific system software and Macintosh computers update their systems with System 7.5.3 Revision 2. There is no benefit for other customers.

The only systems which will benefit from System 7.5.3 Revision 2 are as follows:

• All PowerBook systems using Connectix RAM Doubler
• All PowerBook 5300 and PowerBook Duo 2300 systems
• All PowerBook 200 or 500 Series systems which have been upgraded with the Macintosh PowerBook Processor Card Upgrade Kit with PowerPC (or upgraded with similar third party products).
• All Macintosh 7200, 7500, 7600, 8500, and 9500 systems

You should install System 7.5.3 Revision 2 only if you have a computer with System 7.5.3 installed or a PowerBook with System 7.5.2, PowerBook Enabler 1.2 or later installed. To find out what system software version your computer is using, follow these steps:
