&lt;/h1&gt;
 &lt;blockquote&gt;
 &lt;p&gt;&lt;strong&gt;Target OS:&lt;/strong&gt; Ubuntu 24.04 LTS (Noble Numbat)
&lt;strong&gt;Role:&lt;/strong&gt; High-Memory Computing Node / AI Prototyping Workstation&lt;/p&gt;

 &lt;/blockquote&gt;
&lt;p&gt;::: info HARDWARE OVERVIEW
Il Mac Pro 2013 utilizza un&amp;rsquo;architettura basata su workstation Intel Ivy Bridge-EP.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;CPU:&lt;/strong&gt; Intel Xeon E5 (multi-core, alta cache L3).&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;RAM:&lt;/strong&gt; 96GB DDR3 ECC (fondamentale per caricare modelli LLM pesanti in RAM).&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;GPU:&lt;/strong&gt; Dual AMD FirePro (D300/D500/D700).&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Storage:&lt;/strong&gt; SSD PCIe proprietario (spesso aggiornato con adattatori NVMe).
:::&lt;/li&gt;
&lt;/ul&gt;
&lt;h2 id="1-fase-di-installazione--boot"&gt;1. Fase di Installazione &amp;amp; Boot
&lt;/h2&gt;&lt;p&gt;A differenza dei PC standard, il Mac Pro richiede un&amp;rsquo;attenzione particolare al bootloader EFI.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;EFI Compatibility:&lt;/strong&gt; Ubuntu 24.04 riconosce nativamente il firmware Apple. Non è necessario usare rEFInd a meno di non voler gestire un dual-boot complesso.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Kernel Version:&lt;/strong&gt; Ubuntu 24.04 monta il kernel 6.8+, che include driver migliorati per la gestione degli stati energetici delle CPU Xeon v2.&lt;/li&gt;
&lt;/ul&gt;
&lt;hr&gt;
&lt;h2 id="2-gestione-termica-critico"&gt;2. Gestione Termica (Critico)
&lt;/h2&gt;&lt;p&gt;Linux, di default, non gestisce correttamente la curva della ventola del Mac Pro, rischiando il surriscaldamento sotto carico (specialmente con 96GB di RAM che generano calore).&lt;/p&gt;
&lt;h3 id="installazione-di-macfanctld"&gt;Installazione di &lt;code&gt;macfanctld&lt;/code&gt;
&lt;/h3&gt;&lt;p&gt;È obbligatorio installare un demone specifico per regolare la ventola basandosi sui sensori Apple:&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-text-size-adjust:none;"&gt;&lt;code class="language-bash" data-lang="bash"&gt;&lt;span style="display:flex;"&gt;&lt;span&gt;&lt;span style="color:#75715e"&gt;# Installazione utility sensori e controllo ventole&lt;/span&gt;
&lt;/span&gt;&lt;/span&gt;&lt;span style="display:flex;"&gt;&lt;span&gt;sudo apt update
&lt;/span&gt;&lt;/span&gt;&lt;span style="display:flex;"&gt;&lt;span&gt;sudo apt install lm-sensors macfanctld -y
&lt;/span&gt;&lt;/span&gt;&lt;span style="display:flex;"&gt;&lt;span&gt;
&lt;/span&gt;&lt;/span&gt;&lt;span style="display:flex;"&gt;&lt;span&gt;&lt;span style="color:#75715e"&gt;# Configurazione sensori&lt;/span&gt;
&lt;/span&gt;&lt;/span&gt;&lt;span style="display:flex;"&gt;&lt;span&gt;sudo sensors-detect --auto
&lt;/span&gt;&lt;/span&gt;&lt;span style="display:flex;"&gt;&lt;span&gt;
&lt;/span&gt;&lt;/span&gt;&lt;span style="display:flex;"&gt;&lt;span&gt;&lt;span style="color:#75715e"&gt;# Configurazione demone&lt;/span&gt;
&lt;/span&gt;&lt;/span&gt;&lt;span style="display:flex;"&gt;&lt;span&gt;sudo nano /etc/macfanctl.conf
&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;&lt;strong&gt;Configurazione consigliata per Workstation:&lt;/strong&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;code&gt;temp_avg_floor&lt;/code&gt;: 45&lt;/li&gt;
&lt;li&gt;&lt;code&gt;temp_avg_ceiling&lt;/code&gt;: 80&lt;/li&gt;
&lt;li&gt;&lt;code&gt;fan_min&lt;/code&gt;: 1000 (leggermente superiore al default per preservare i componenti).&lt;/li&gt;
&lt;/ul&gt;
&lt;hr&gt;
&lt;h2 id="3-configurazione-dual-gpu-amd-firepro"&gt;3. Configurazione Dual GPU (AMD FirePro)
&lt;/h2&gt;&lt;p&gt;Ubuntu utilizza i driver open-source &lt;strong&gt;Mesa (RadeonSI)&lt;/strong&gt;. In ambiente Linux, il Crossfire non esiste come su Windows, ma le due schede sono viste come dispositivi indipendenti.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Compute:&lt;/strong&gt; Entrambe le GPU possono essere utilizzate per calcoli OpenCL o tramite librerie ROCm (sebbene il supporto per le vecchie generazioni GCN sia limitato).&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Display:&lt;/strong&gt; Ubuntu gestisce automaticamente il desktop esteso su tutte le porte Thunderbolt (Mini DisplayPort) e HDMI.&lt;/li&gt;
&lt;/ul&gt;

&lt;/h2&gt;&lt;h3 id="a-swap--zram"&gt;A. Swap &amp;amp; ZRAM
&lt;/h3&gt;&lt;p&gt;Con 96GB di RAM, lo swap su disco è quasi inutile, ma per carichi IA estremi, configuriamo la &lt;strong&gt;ZRAM&lt;/strong&gt; per evitare colli di bottiglia:&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-text-size-adjust:none;"&gt;&lt;code class="language-bash" data-lang="bash"&gt;&lt;span style="display:flex;"&gt;&lt;span&gt;sudo apt install zram-config -y
&lt;/span&gt;&lt;/span&gt;&lt;span style="display:flex;"&gt;&lt;span&gt;&lt;span style="color:#75715e"&gt;# Linux userà una porzione della RAM compressa come swap ultra-veloce.&lt;/span&gt;
&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;h3 id="b-nvme-power-management"&gt;B. NVMe Power Management
&lt;/h3&gt;&lt;p&gt;Se hai sostituito l&amp;rsquo;SSD originale con un NVMe moderno tramite adattatore, aggiungi questo parametro al GRUB per evitare crash durante il deep sleep:
&lt;code&gt;nvme_core.default_ps_max_latency=0&lt;/code&gt;&lt;/p&gt;
&lt;hr&gt;
&lt;h2 id="-perché-questa-macchina-nel-2026"&gt;💡 Perché questa macchina nel 2026?
&lt;/h2&gt;&lt;p&gt;Dal punto di vista dell&amp;rsquo;architettura software, il Mac Pro 2013 con Linux è perfetto per:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;&lt;strong&gt;NODO LLM Locale:&lt;/strong&gt; I 96GB di RAM permettono di far girare modelli come &lt;strong&gt;Llama-3-70B&lt;/strong&gt; (quantizzato) interamente in memoria di sistema.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Compilation Server:&lt;/strong&gt; La stabilità della memoria ECC previene errori di segmentazione durante compilazioni C++ massive.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Home Assistant Proxmox Backup:&lt;/strong&gt; Se non usato come workstation, può diventare un server Proxmox secondario di altissima affidabilità.&lt;/li&gt;
&lt;/ol&gt;
