The previous version is still active as determined by a LaTeX run.</div><div class=""><br class=""></div><div class="">3) On the laptop I tried updating 2020. Said it cannot do it because current version is 2021. I tried update of 2019. It started (tried twice) and it “failed” both times. Several errors. When I try compile a program under 2019 it is now unusable: “missing ifxetex.sty” it complains.</div><div class=""><br class=""></div><div class="">4) I cannot run 2021 on the laptop. The Utility thinks I am in 2020 (it lists 2021 but this is not real; 2020 is). </div><div class=""><br class=""></div><div class="">5) Unfortunately I cannot use the old “LocalTeX” app to switch to 2021. This version is not even acknowledged but it is there all right. All I got is a broken TeX Utility…or something else is broken.</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Any fix? I did not do anything differently in the laptop than I did in the desktop (except for the different OS X in the two).</div><div class=""><br class=""></div><div class="">Thanks,</div><div class="">George<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Jun 28, 2021, at 6:32 PM, Herbert Schulz <<a href="mailto:herbs@wideopenwest.com" class="">herbs@wideopenwest.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><br style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 18px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;" class=""><br style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 18px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;" class=""><br class="Apple-interchange-newline"></div></blockquote></div><br class=""></div></div></body></html>
