Apple has signed drivers for Nvidia eGPU Mac compatibility, allowing external GPUs from both Nvidia and AMD to work on Apple silicon devices for the first time without workarounds. Tiny Corp, the company behind the tinybox AI accelerator, said on April 1, 2026 that Apple approved the drivers, enabling users to pair external GPUs with Macs for AI large language model processing.
The approval removes a significant barrier for Mac users. Previously, running an eGPU on Apple silicon required disabling System Integrity Protection, a security feature Apple strongly discourages bypassing. Tiny Corp first tested an eGPU on Apple silicon in May 2025, but official driver support was absent until now.
What the Nvidia eGPU Mac Driver Actually Does
The driver is built specifically for artificial intelligence workloads, particularly running and training large language models. It does not support gaming, which limits its appeal to users who want a single machine for both productivity and entertainment. Tiny Corp noted the installation process is now straightforward, describing it as simple enough for an LLM to complete.
Tiny Corp’s Hardware Lineup
Tiny Corp sells two AI accelerator products. The tinybox red v2 runs on four AMD Radeon RX 9070 XT GPUs and costs $12,000. The tinybox green v2 Blackwell carries four RTX Pro 6000 Blackwell GPUs and is priced at $65,000. The company is also planning a product called the exabox, expected in 2027, which will include 720 RDNA5 AT0 XL GPUs and deliver approximately 1 exaflop of computing power at a price of around $10 million.
“If you have a Thunderbolt or USB4 eGPU and a Mac, today is the day you’ve been waiting for. Apple finally approved our driver for both AMD and NVIDIA.”

Mac Demand Surge Tied to AI Agents
High-end Apple computers have seen rising demand alongside the growth of AI agents. This demand has created a shortage of Mac models with large Unified Memory configurations, pushing delivery windows from six days to six weeks. Apple has also removed the 512GB Unified Memory option from the Mac Studio entirely, while the 256GB model received a $400 price increase.
Context and Limitations
Tiny Corp developed the driver independently, without involvement from Nvidia or AMD. Because the driver targets AI inference and training rather than graphics rendering, it does not address the needs of users who want gaming performance on a Mac. However, for professionals working with AI models, the update means they can now run training or inference tasks on a Mac paired with an external GPU, without purchasing a dedicated AI computing system.
Tiny Corp’s history with GPU makers includes a notable dispute with AMD over driver issues, which required AMD CEO Dr. Lisa Su to intervene directly to resolve the situation.
