&lt;p&gt;I saw the error but the DFU libraries just skip bootloader and SD if they are the same version instead of failing with error, which is helpful as you don&amp;rsquo;t need to know if they are the same version in advance as use a package with only App.&lt;/p&gt;
&lt;p&gt;as for the serial number issue it works fine on Windows so would seem like a bug on the macos version.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nrfutil dfu ble timeout</title><link>https://devzone.nordicsemi.com/thread/291431?ContentTypeID=1</link><pubDate>Wed, 27 Jan 2021 07:55:30 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:211ec5eb-8b43-42d3-bec6-26d8557f6c46</guid><dc:creator>Amanda Hsieh</dc:creator><description>&lt;p&gt;Hi Nick,&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Good to know it can work now.&lt;/p&gt;
[quote user="nrbrook"]But if the zip also contains BL and SD which don&amp;#39;t have higher versions, it fails with an error instead of skipping these like the DFU libraries do. I can&amp;#39;t see an option to control this behaviour. [/quote]
&lt;p&gt;The util reflects this as the error message indicates&lt;/p&gt;
&lt;p&gt;&lt;em&gt;Extended Error 0x05: The firmware version is too low. For an application, the version must be greater than or equal to the current application. For a bootloader, it must be greater than the current version. This requirement prevents downgrade attacks.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;As for&amp;nbsp;&lt;span&gt;the serial number, the second log indicates that&amp;nbsp;&lt;/span&gt;Board not found: {}&amp;quot;.format(serial_port or snr). It is hard to say why the&amp;nbsp;&lt;span&gt;serial_port&amp;nbsp;doesn&amp;#39;t work on your MAC but&amp;nbsp;the serial number could. Sorry, I don&amp;#39;t familiar with MacOS.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;span&gt;It worked for someone else having some problems with Mac and nrfutil.&amp;nbsp;&lt;/span&gt;&lt;span&gt;If it still cannot find the board, you might try to reboot the Mac and do it again.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
