&lt;blockquote class="border-l-4 border-neutral-300 dark:border-neutral-600 pl-4 italic text-neutral-600 dark:text-neutral-400 my-6"&gt;
&lt;p&gt;When we are born, we cry that we are come to this great stage of fools.&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;The year 2026 kicked off with a bold statement: &amp;ldquo;What if time&amp;hellip; just stopped working?&amp;rdquo;&lt;/p&gt;
&lt;p&gt;First, League of Legends players around the world found themselves locked out for hours because an SSL certificate quietly expired. No dragons, no Baron, just TLS saying nope.&lt;/p&gt;
&lt;p&gt;Then, not wanting to be left out, Logitech decided to add some cross-industry solidarity. As shown in the screenshot, Logi Options+ on macOS strikes. Purple screen with a loading circle. No mouse customisation enlightenment. 😇&lt;/p&gt;
&lt;p&gt;
&lt;figure &gt;
&lt;div class="flex justify-center "&gt;
&lt;div class="w-full" &gt;
&lt;img alt="Logi Options&amp;#43; on macOS stuck loading forever."

&lt;/div&gt;&lt;/figure&gt;
&lt;/p&gt;
&lt;p&gt;Digging a little deeper, the issue turns out to be painfully familiar: a certificate expired at exactly the start of 2026.&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre tabindex="0" class="chroma"&gt;&lt;code class="language-sh" data-lang="sh"&gt;&lt;span class="line"&gt;&lt;span class="cl"&gt;codesign -d --extract-certificates /Applications/logioptionsplus.app
&lt;/span&gt;&lt;/span&gt;&lt;span class="line"&gt;&lt;span class="cl"&gt;&lt;span class="k"&gt;for&lt;/span&gt; f in codesign*&lt;span class="p"&gt;;&lt;/span&gt; &lt;span class="k"&gt;do&lt;/span&gt;
&lt;/span&gt;&lt;/span&gt;&lt;span class="line"&gt;&lt;span class="cl"&gt; &lt;span class="nb"&gt;echo&lt;/span&gt; &lt;span class="s2"&gt;&amp;#34;== &lt;/span&gt;&lt;span class="nv"&gt;$f&lt;/span&gt;&lt;span class="s2"&gt; ==&amp;#34;&lt;/span&gt;
&lt;/span&gt;&lt;/span&gt;&lt;span class="line"&gt;&lt;span class="cl"&gt; openssl x509 -inform DER -in &lt;span class="s2"&gt;&amp;#34;&lt;/span&gt;&lt;span class="nv"&gt;$f&lt;/span&gt;&lt;span class="s2"&gt;&amp;#34;&lt;/span&gt; -noout -dates
&lt;/span&gt;&lt;/span&gt;&lt;span class="line"&gt;&lt;span class="cl"&gt;&lt;span class="k"&gt;done&lt;/span&gt;
&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;
&lt;figure &gt;
&lt;div class="flex justify-center "&gt;
&lt;div class="w-full" &gt;
&lt;img alt="Logi Options&amp;#43; on macOS is signed with a certificate expired at the start of 2026."
srcset="https://www.isarvin.com/blog/interesting-start-to-2026/cert-expiry-evidence_hu_4701e6347c81786f.webp 320w, https://www.isarvin.com/blog/interesting-start-to-2026/cert-expiry-evidence_hu_5d005fc0d4e6d4e3.webp 480w, https://www.isarvin.com/blog/interesting-start-to-2026/cert-expiry-evidence_hu_b666a064841d15cc.webp 512w"

loading="lazy" data-zoomable /&gt;&lt;/div&gt;
&lt;/div&gt;&lt;/figure&gt;
&lt;/p&gt;
&lt;p&gt;macOS, being very strict about reality, looks at the clock, looks at the certificate, and says: &amp;ldquo;This app lives in the past. I refuse.&amp;rdquo; 🧐&lt;/p&gt;
&lt;p&gt;Until Logitech remembers how calendars work, the workaround is gloriously low-tech. Just set the system time to before 20:39 GMT on 6 January 2026. It may also be necessary to restart the Logi Plugin Service. After that, congratulations: you have successfully debugged time!&lt;/p&gt;
&lt;p&gt;So here we are, early 2026:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;Gamers defeated by certificates.&lt;/li&gt;
&lt;li&gt;A utility app halted by GMT.&lt;/li&gt;
&lt;li&gt;Engineers everywhere muttering: &amp;ldquo;How did this pass CI?&amp;rdquo;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;What&amp;rsquo;s next? 😈&lt;/p&gt;
&lt;p&gt;Anyway, happy New Year! Of course, don&amp;rsquo;t forget to renew your certificates. ⏰&lt;/p&gt;</description></item></channel></rss>
