<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><DIV>Summary</DIV><DIV>-------</DIV><DIV>Since the release of Mac OS X 10.4 "Tiger" on April 29, IS&T, in collaboration with other departments, labs and centers, has done a thorough investigation of what it offers, which is quite a lot. Spotlight, Dashboard, VoiceOver and Automator are some of the features that will prove to be very useful in the MIT environment as Tiger matures.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>With any new operating system, especially one that has as many under-the-hood changes as Tiger, there are going to incompatibilities and bugs. About two weeks after Tiger was released, Apple released Mac OS X 10.4.1, which fixed many issues (see below). It's likely that Apple will release frequent updates as they did when 10.2 and 10.3 were initially released.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Information Services and Technology recommends that administrative users, especially those that depend on SAPgui for Mac OS X should not upgrade to Tiger at this time. No version of SAPgui functions properly on Tiger--some transactions don't work or can cause SAPgui to crash or corrupt data. While Apple and SAP are working on the issues, no one has offered an estimate for when the issues will be resolved. Some SAP users can use SAPweb or Citrix (to access the Windows version of SAP) until SAP works properly on Tiger; please see the Mac OS X release notebook (<A href="http://web.mit.edu/swrt/releases/macosx10.4/">http://web.mit.edu/swrt/releases/macosx10.4/</A>) for additional information.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>In addition, departments, labs and centers that rely on VPN, Kerberos authentication at login or OpenAFS should not upgrade to Mac OS X 10.4 at this time, as these applications and features don't currently work and we don't have a timeframe when they will.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>IS&T continues to gear up support for Mac OS X 10.4. Support from the Computing Help Desk is currently limited to help getting connected to MITnet and basic configuration issues. As supported application issues become resolved, more in-depth support will be available.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Below are details on application and operating system issues in Tiger. Please contact the Mac OS X release team at <A href="mailto:macosx-release@mit.edu">macosx-release@mit.edu</A> if you have further questions.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Supported Application Issues</DIV><DIV>----------------------------</DIV><DIV>* SAPgui</DIV><DIV>We expect a future version of Mac OS X 10.4's Java Runtime Environment to</DIV><DIV>address some reported problems and allow SAP to release SAPgui 6.40 for Tiger.</DIV><DIV>(It is possible that Apple could correct problems in a different version of the</DIV><DIV>Mac OS X 10.4 Java Runtime Environment which would allow an earlier version of</DIV><DIV>the SAPgui to run on Tiger - but neither Apple nor SAP have committed that they</DIV><DIV>will do this.)</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>* Virex</DIV><DIV>Virex 7.2.1 works on Mac OS X 10.4. However, the newest versions (7.5.1 and 7.6) are not compatible with Mac OS X 10.4. McAfee has indicated that version 7.7 will be compatible, but has not announced when it will be available.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>* VPN</DIV><DIV>Cisco has released version 4.6.03 of their virtual private network (VPN) client, which is now compatible with Mac OS X 10.4. However, this version works only on single processor machines--dual processor machines are not supported. IS&T expects to release this version of the VPN client soon and will follow up with the dual processor version when it is available.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Operating System Update and Issues</DIV><DIV>----------------------------------</DIV><DIV>* Kerberos authentication at login</DIV><DIV>Several departments take advantage of a feature of Mac OS X (10.2 or greater) that grants Kerberos tickets to a user upon a successful login when using their Kerberos principal and password. This feature isn't currently available in Mac OS X 10.4. In addition, upgrading a 10.3 machine that uses this feature to 10.4 disables the ability to login to the machine at all. MIT's Kerberos development team and Apple are working to resolve this problem.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>* Certificates</DIV><DIV>Mac OS X 10.4 adds more stringent handling of certificates compared to previous versions of Mac OS X. As a result, while certificates work, enabling Safari and Mail to work securely, the default behavior is not to recognize the MIT Certificate Authority (also known as the MIT CA) as trusted. We are investigating methods for resolving this issue.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>* OpenAFS</DIV><DIV>OpenAFS is an open-source software project that enables Mac OS X users to use AFS, a network filesystem. MIT's Athena uses AFS; OpenAFS allows users to easily access their Athena home directories, for example. At this time, OpenAFS doesn't work on Mac OS X 10.4. A future version of OpenAFS is expected to function properly on 10.4.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>* 10.4.1</DIV><DIV>On May 16, Apple released Mac OS X 10.4.1 which includes improvement for:</DIV><DIV> - file sharing using AFP and SMB/CIFS network file services</DIV><DIV> - using DHCP in wireless networks</DIV><DIV> - user login when accessing LDAP and Active Directory servers</DIV><DIV> - core graphics including updated ATI and NVIDIA graphics drivers</DIV><DIV> - synchronization with .Mac</DIV><DIV> - Address Book, iCal, Font Book, Mail, and Preview applications</DIV><DIV> - Dashboard widgets: Address Book, Flight Tracker, Phone Book, and</DIV><DIV> World Clock</DIV><DIV> - compatibility with third party applications and devices</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Detailed information on 10.4.1 is available at <A href="http://www.info.apple.com/kbnum/n301517">http://www.info.apple.com/kbnum/n301517</A>.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Al Willis, for the Mac OS X release team</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV> Deb Bowser</DIV><DIV> Joey Gottinger</DIV><DIV> Jonathan Reed</DIV><DIV> Lee Ridgway</DIV><DIV> Helen Rose</DIV><DIV> Matthias Thorn</DIV><DIV> Karl Witt</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR class="khtml-block-placeholder"></DIV><BR><DIV> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Lucida Grande" size="3" style="font: 11.0px Lucida Grande">______________________________</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Lucida Grande" size="3" style="font: 11.0px Lucida Grande">Albert Willis</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Lucida Grande" size="3" style="font: 11.0px Lucida Grande">Macintosh Platform Coordinator - Software Release Team</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Lucida Grande" size="3" style="font: 11.0px Lucida Grande">Information Services and Technology</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Lucida Grande" size="3" style="font: 11.0px Lucida Grande">Massachusetts Institute of Technology</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Lucida Grande" size="3" style="font: 11.0px Lucida Grande"><A href="mailto:awillis@mit.edu">awillis@mit.edu</A></FONT></P> </DIV><BR></BODY></HTML>
