CostGraph shows the details a Mac reports and leaves out the charts that only Linux hosts produce. ## Find your Macs A Mac you own lists **Apple** as its provider. A Mac you rent from a cloud keeps that cloud as its provider, such as **AWS** for an EC2 Mac. The Apple mark next to the type identifies every Mac, whoever hosts it. The **Type** column shows the chip of a Mac you own, such as Apple M4 Pro, with **Owned** as its pricing model. A rented Mac shows the instance type and pricing model its cloud bills. For a Mac you own, the line under its name shows its model. After your organization adds a Mac, the list shows four filters: * **Platform** selects Macs or Linux hosts. * **Chip** selects a chip, such as Apple M2. * **Model** selects a model, such as Mac mini. * **macOS version** selects a macOS release. The filters scope the list, **VM spend**, and the top contributors. ## Mac details The header shows the Mac's **CPU cores** and **Unified memory**. The tabs are **Overview** and **Metrics**. **Overview** shows the Mac's **Model**, **Chip**, **macOS version**, and **Darwin version** among its details. A Mac you own has no instance type, region, or usage type, so those details are left out. ## Cost basis CostGraph prices a Mac you own from its model's list price in the CostGraph price catalog. The price is spread over the months the catalog sets for that model. The **Cost basis** detail on the overview names the source of the hourly cost: | Cost basis | Meaning | | - | - | | **List price \$1,399 USD spread over 36 months** | The catalog list price for this model, spread over its expected life. List prices are in US dollars, whatever currency your organization uses. | | **Catalog rate** | A catalog rate priced the Mac. | | **Your pinned price** | A price you assigned to this Mac. | | **No matching price yet** | No price matched this Mac. | **Cost / hour** shows the hourly cost CostGraph assigns to the Mac. To cost a Mac at your own figure, such as what you paid or a hosting contract, assign it one of your organization's prices. Set the **Price** field on the Mac's overview, or tag the Mac with a pricing ID through the API. The Mac is costed at that price from the next hour, and **Cost basis** reads **Your pinned price**. See [Assign a price to a virtual machine](/costgraph/operator/on-prem-pricing#assign-a-price-to-a-virtual-machine). ## Memory pressure and thermal state Two cards under **System cost** show the Mac's latest memory pressure and thermal state, as macOS reports them: | Memory pressure | Meaning | | - | - | | **Normal** | Memory is available for new work. | | **Warning** | macOS is compressing memory or swapping to keep up. | | **Critical** | Memory is exhausted, and apps slow down. | | Thermal state | Meaning | | - | - | | **Nominal** | The Mac runs at full speed. | | **Fair** | The Mac is slightly warmer than normal. | | **Serious** | macOS reduces performance to cool the Mac. | | **Critical** | macOS reduces performance sharply to protect the hardware. | The memory pressure card also shows the Mac's unified memory. A card reads **Not reported by this Mac yet** until the agent sends its first reading. The usage heatmap adds **Memory pressure** and **Thermal** tabs beside **CPU** and **Memory**. Each cell shows the worst level the Mac reached in that hour, so a short spike is not hidden by a calm hour around it. Every level except the calm one carries a pattern, so the grid reads without color. **Hottest window** names the hour with the worst level and that level. ## Metrics on a Mac **Metrics** charts the same ranges as for other machines. Memory is labeled unified memory, disk usage is the APFS container, and network traffic counts physical interfaces only. macOS does not report the following, so the Mac pages leave them out: * The **Containers** and **GPUs** tabs, and the container runtime and running containers details. * The GPU section of **Metrics**. * CPU steal, IO wait, and interrupt time. * CPU, memory, and IO pressure stall charts. Memory pressure takes their place. * Disk throughput, IO operations, IO latency, and busy time. * Buffered and cached memory, and TCP retransmits. When you compare a Mac with a Linux host in **Metrics**, CostGraph shows every chart. The charts a Mac does not report show no data for the Mac. ## Next steps The fleet view, recommendations, and the details every machine shares. Register your own rates and assign them to machines.
